An animal that eats only plants is called a: (a) Carnivore (b) Herbivore (c) Omnivore (d) Decomposer

Which of these is an example of a scavenger? (a) Deer (b) Tiger (c) Vulture (d) Bear

The process by which plants make their own food using sunlight, water, and carbon dioxide is called: (a) Respiration (b) Digestion (c) Photosynthesis (d) Decomposition

What do animals breathe out that plants need for photosynthesis? (a) Oxygen (b) Carbon Dioxide (c) Nitrogen (d) Water Vapour

2. Fill in the Blanks:

All living beings need ............... to stay alive.

Animals that eat both plants and other animals are called ................. .

Bacteria and fungi are examples of ............... that break down dead plants and animals.

A ............... shows the flow of food energy between different living things, like grass being eaten by a deer, which is then eaten by a lion.

Many interconnected food chains in an ecosystem make a ................. .

Plants depend on animals like bees and butterflies for ..............., which helps them produce fruits.

3. True/False Questions: (Write 'True' or 'False')

Animals can produce their own food. (................)

A lion is an example of a herbivore. (................)

Decomposers return nutrients to the soil by breaking down dead organisms. (................)

The balance of nature is not affected if one species in a food chain disappears. (................)

Air, water, and soil are living components of the environment. (................)

4. Short Answer Questions:

What are consumers? Give one example.

____________________________________________________________________________________________________________

Besides food and oxygen, name one other way animals depend on plants.

____________________________________________________________________________________________________________

What is the main difference between a herbivore and a carnivore?

____________________________________________________________________________________________________________

List one natural cause and one human-made cause of imbalance in nature.

____________________________________________________________________________________________________________

How do animals help plants with seed dispersal?

____________________________________________________________________________________________________________

5. Diagram-Based Questions:

Diagram 1:

⁠

⁠

a. What does this diagram represent?

____________________________________________________________________________________________________________

b. Identify the producer in this diagram.

____________________________________________________________________________________________________________ c. If all the frogs were removed, which animal population might increase, and which might decrease?

____________________________________________________________________________________________________________

Diagram 2:

⁠

a. What is the difference between this diagram (a food web) and a single food chain?

____________________________________________________________________________________________________________ b. From a typical food web like this, name one omnivore and what it might eat.

____________________________________________________________________________________________________________

6. Scientific Reasons:

Why are plants essential for the survival of animals on Earth? (Give at least two key reasons related to what plants provide).

____________________________________________________________________________________________________________

Why are decomposers called "nature's recyclers"?

____________________________________________________________________________________________________________

Why do plants need non-living things like sunlight and water?

____________________________________________________________________________________________________________

7. Differentiate Between Concepts:

Explain the difference between a producer and a consumer, giving an example of each.

____________________________________________________________________________________________________________

Explain the difference between a scavenger and a carnivore (that hunts live prey).

____________________________________________________________________________________________________________

8. Explanations of Terms:

Define 'photosynthesis'.

____________________________________________________________________________________________________________

Define 'interdependence' in the context of plants and animals in an ecosystem.

____________________________________________________________________________________________________________

Define 'food web'.

____________________________________________________________________________________________________________

9. Examples:

Give two examples of omnivores mentioned in your chapter.

____________________________________________________________________________________________________________

Give one example of how an animal helps a plant in pollination.

____________________________________________________________________________________________________________

Give two examples of decomposers.

____________________________________________________________________________________________________________

10. Complete the Series:

A deer eats grass, and a tiger eats the deer. What is this sequence called, and what fundamental thing does it show the movement of?

____________________________________________________________________________________________________________

When birds eat fruits and then fly to different places, they excrete the seeds. What important process for plants are the birds helping with? Explain its importance.

____________________________________________________________________________________________________________

12. Observation-Based Questions:

If you observe a fallen log in a forest slowly breaking down and becoming part of the soil over many months, what group of organisms is mainly responsible for this change? What is this process called?

____________________________________________________________________________________________________________

Imagine a large area of forest is cleared for building houses (deforestation). What are two likely effects you would observe on the local animal populations that depended on that forest?

____________________________________________________________________________________________________________

13. Scientific Reasoning and Application:

If a new, unknown disease suddenly killed all the green plants in an area, explain the step-by-step impact this would have on the herbivores and then the carnivores in that area.

____________________________________________________________________________________________________________

Your chapter mentions earthworms are used in "vermicomposting." Based on what you learned about decomposers, explain how earthworms help in making manure from wet garbage.
