Std 5 EVS 1 Chapter 4 Question Answer

1. What’s the solution?

Question 1.
We have to remove insects from the grains without using pesticides.
Answer:
Some plants like neem or their extract repel insects. That is insects run away from these substances. Hence if we place dried leaves of neem. The grains will be freed from the insects as they will go away. Similarly it is by applying canola oil to the grains we can remove the insects as canola oil is also an insect repellent.

2. Use your brain power.

Question 1.
Use your brain power.
Make up a food chain:
Frog, Kite, Worm, Snake, Grass
Answer:
Grass → Worm → Frog → Snake → Kite

3. Answer the following questions:

Question (a)
What is a food chain? Give an example of it.
Answer:
In nature, Plants are food for one small animal. This smaller animal is the food for a larger animal which in turn is a food for another larger animal. Thus we see that one living thing is connected to another living thing for their food, and each component or living thing is the food for the next one. Therefore we can say the components form a chain. Such a biological chain is called a food chain. Example of a food chain.

Plants → Grasshopper → Frog → Snake → Kite

The plant is eaten by the grasshopper which is eaten by the frog. The frog is eaten by the snake which is eaten by the kite.

Question (b)
How is the balance in the environment maintained?
Answer:
1. Plants use substances in the soil for their growth and when plants and animals die the micro-organisms decompose them and this added to the substances goes back to the soil once again.
2. Similarly the water cycle maintains a continuous supply of water for all the living things.
3. Living things take in oxygen and give out carbon dioxide while breathing. The plants take in carbon dioxide and give out oxygen while preparing their food. Thus oxygen gets added to the air.

There are several other such cycles which go on in nature due to interaction amongst living things. When such interactions and cycles go on uninterrupted continuously, they help in maintaining the food chain. Due to this, environmental balance is maintained.

4. What substances in the soil are useful for the growth of plants?

Question 1.
What substances in the soil are useful for the growth of plants?
Answer:
The plants use substances like water, minerals and organic matter from the soil for their growth.
Note: Grasshopper does not feed on worms. It is not a flesh eating insect. It eats only various parts of plants like seeds & leaves. The first image shown in the textbook on page 20 is of an insect called cricket, which feeds on worms, and the bird feeds on this cricket.
Hence the correct food chain is
grass → worm → cricket (insect) → bird

5. True or false?

Question 1.
True or false?

1. Microorganisms form a part of the environment.
2. It is necessary to maintain biodiversity.
3. A grasshopper eats birds.

Answer:

1. True

Give reasons:

Question 1.
Plants are the main support of every food chain.
Answer:
Many animals in the environment eat only plants. Some animals eat smaller animals that live on plants. Plants make their own food using water from soil and carbon dioxide from air in the presence of sunlight. They are the only living organisms which do not depend for their food on other animals. All other animals directly or indirectly depend on plants for food. Hence, plants are the main support of every food chain.

Question 2.
It is important to maintain the environmental balance for existence of living things.
Answer:
When various cycles present in nature go on uninterrupted, environmental balance is maintained in nature. This helps in maintaining the food chains in the environment. If environmental balance is not maintained the food chains get affected and some animals may die due to shortage of food. If this continues, it will destroy nature and all the living things. Therefore, to maintain the food chains and existence of living things environmental balance should be maintained.

State how the following non-living things found in nature are useful to living things:

Question 1.
Hollow of a tree:
Answer:
Many animals like squirrels, birds etc. take shelter in the hollow of the tree. Insects also are known to be found in this hollow.

Question 2.
Rocks:
Answer:
Small rocks present in the soil help the roots of the plant to breathe and grow as they allow air and water to pass through the soil. Soil which helps plant to grow is formed by breaking down of these rocks. Many insects also take shelter under large rocks e.g. Scorpions live below the rocks.

Question 3.
Sun:
Answer:
The Sun is the source of energy. It provides sunlight. Plants cannot grow without sunlight. Hence no life would exist without the Sun.

Question 4.
Mountains:
Answer:
Large forests are found on mountains. Rivers also originate in mountains. Hence, mountains are homes for many living things. They are homes for many birds, monkeys, wild animals etc.

Answer the following questions:

Question 1.
What do you mean by a link in a food chain? If one of the links in a chain is lost from the chain, can the food chain last? Explain.
Answer:
In a food chain, one animal is the food for the next animal. Each one of the living things forming a food chain is called the link of the food chain. If one link of the food chain is lost it will affect the next link. It means if one animal is lost, the next animal for which it is the food will also get affected, as it will cause shortage of food.

This will lead to starvation8 and death of the animals in the next link. For Example: If deer disappear from the forest, the lions and tigers will starve for food and they will die. Thus we see that the food chain will not last if one link in the food chain is lost.

Question 2.
Who eats birds?
Answer:
Birds are eaten by various animals depending on their size. Small birds like sparrow, robins, canary etc. are eaten by snakes. Pythons can eat large birds like herons, stork, etc. by coiling around them and crushing them. Dogs, cats also eat birds like chicken, hens etc. Some large birds eat the young ones of birds or smaller birds.

For example: kite, eagle, owls, falcons eat small birds or young ones of other birds. Foxes, racoons, coyotes are wild animals which eat small birds and other birds like owls. Lastly human beings also eat birds like, chicken, turkey, duck as food. Birds like eagles, kite and vultures are not eaten by any animals. Microorganisms decompose them after they die.

Question 3.
Explain how the balance in the level of oxygen and carbon dioxide present in the air is maintained in nature.
Answer:
The animals take in oxygen and give out carbon dioxide while breathing. However plants take in carbon dioxide and give out oxygen while preparing food. Due to this process the balance in the level of oxygen and carbon dioxide present in the air is maintained.

Question 4.
Describe the water cycle present in nature.
Answer:
Our earth is covered with water bodies. The heat of the sun evaporates the water from the water bodies like sea, lake, ponds stveanes of rivers and also the water which has percolated beneath the soil. This evaporated water vapour is light, so it moves up into the higher and cooler atmosphere to form fine drops of water which float.

These smaller drops form clouds. They later join together to form big and heavy drops; which fall down as rain. The rain water goes back to the water bodies, thus the process of condensation, evaporation and rainfall continue to form a water cycle.

Observe the picture given below and answer the following:

Question (A)
Find the different food chains of whichthe worm and the mouse form a link:
Answer:
There are two food chains as shown below :

Question (B)
Find the different food chains where the fox and lion form a link.

Answer:

Question 2.
Draw a diagram showing the oxygen cycle:
Answer:

What’s the solution?

Question 1.
Mosquitoes cause malaria. To prevent malaria mosquitoes need to be stopped from growing.
Answer:
Mosquitoes larvae grow in water. Hence to prevent them from growing we should not allow water to accumulate. We should keep our surroundings dry. Also fishes like guppies, gold fish and killifish eat up the mosquto larvae. Hence sometimes these fish are grown in ponds to prevent mosquitoes.

Question 2.
The soil is to be made fertile without adding chemical fertilizers.
Answer:
Organic manure is added to the soil. Organic manure is prepared by mixing remains of plants, vegetables, fruits etc. with soil and is allowed to decompose by microorganisms. Microorganisms convert the above substances to organic manure which helps plants to grow.

Can you tell?

Question 1.
What is the deer’s food?
Answer:
The deer feeds on various kinds of plants and grass. They eat leaves, twigs and stems of the plant.

Question 2.
What is food for the tiger?
Answer:
The tiger feeds on plant eating animals like deer, cows, zebra, giraffe, goats, buffaloes, rhinoceros, calf etc.

1. What’s the solution?

Question 1.

Question 1.
Which method of preventing the breeding of mosquitoes will you recommend for your surroundings – not allowing water to stagnate or spraying insecticides on the water? Why?
Answer:
First of all it is better not to allow water to stagnate. Hence I would recommend this method for preventing breeding of mosquitoes. However if there are nullahs or gutters in the surrounding area then spraying insecticide on water will be recommended to kill the mosquito larvae growing in water. Therefore both the methods need to be applied sometimes.

3. Answer the following in one or two sentences:

Answer:
When many people in one area get the same infectious disease at the same time, we say there is an epidemic of the disease. During an epidemic air and water gets contaminated with the disease germs and the disease spreads rapidly. Contaminated water also contaminates the food. If the epidemic is severe many people become serious and need to be hospitalised. To control the epidemic one needs to maintain hygiene and a clean surrounding.

Question (d)
What is vaccination?
Answer:
When a person is given a vaccine against a specific disease, he develops resistance to that disease. This process of giving vaccine is called vaccination. Whooping cough diphtheria and tetanus called triple vaccine is given.

Answer:

6. Give reasons.

Question (a)
When there is an epidemic of cholera, we should boil water before drinking.
Answer:
Sometimes water gets mixed with faeces of person who is suffering from the cholera and it gets contaminated. When people drink this contaminated water an epidemic of cholera spreads.
Boiling the water kills the germs causing the disease and hence one is prevented from getting cholera.
Therefore during an epidemic of cholera one should boil water and drink.

Question (b)
We should not allow puddles of water to stand in our surroundings.
Answer:
When water stagnates in a puddle, mosquitoes lay eggs in the water and they increase in number. Mosquito bite spread malaria germs and people suffer from malaria. To prevent people from getting malaria mosquitoes should be stopped from breeding. To prevent mosquitoes from breeding we should not allow puddle of water to stand in our surrounding.

Answer:
Gastro or diarrhoea spreads through contaminated3 food. When we eat this food the disease spread is called food poisoning.

Question 5.
Why should food always be kept covered?
Answer:
When some flies sit on our food, the germs enter the food. Later when we eat this food the germs enter our body, so we must always cover the food.

Question 6.

Give scientific reasons:

Question 1.
Doctors give tetanus vaccine after getting a cut or wound while handling a sharp instrument or after falling down and getting bruised badly while playing.
Answer:
Tetanus germs are present in the soil, dung and dust. The sharp instrument may be dirty, so it may carry the tetanus germs. These germs may then spread though the wound and cause disease. To prevent tetanus germs from spreading doctors give the vaccine which help us develop resistance against this disease.

Question 2.
A person suffering from a disease should cover the mouth when sneezing or coughing.
Answer:
Disease causing organisms are present in the spit or saliva of the person. When they sneeze or cough these gems spread in the air and cause disease in other people. To prevent the spread of disease through the air a person suffering from a disease should cover the mouth while sneezing or coughing.

Question 3.
Before eating or handling food one should wash the hands using soap and water.
Answer:
Soap kills the germs which cause diseases and water washes them away. If our hand is dirty then they may contain disease causing germs. If we handle food, or eat food without washing, the germs will enter the food and contaminate it with these germs. This can cause intestinal diseases or food poisoning. Hence it is advised that one should wash the hands using soap and water before eating or handling food.

Question 4.
People who are suffering from tuberculosis or swine flu are quarantined and kept in hospitals.
Answer:
The diseases like tuberculosis and swine flu are infectious. They spread through air easily. Also the germs spread cause disease in a healthy person if the healthy person comes in contact directly with the diseased person. In hospitals there are separate wards for such diseased people, where extra care and precautions are taken to prevent spread of diseases. Therefore patients suffering from these diseases are quarantined and kept in hospital.
