1. What do the arrows mean? Circle the answer.

Options:
- eats
- is eaten by

✔ Correct answer: "is eaten by"

Explanation:
In a food chain, the arrow points from the food to the consumer. So, grass → mouse means the mouse eats the grass, or in other words, grass is eaten by the mouse. Therefore, the arrow means "is eaten by".

2. Producers make their own food. What is the producer in this food chain? Circle the answer.

Options:
- grass
- mouse
- owl

✔ Correct answer: grass

Explanation:
A producer is an organism that makes its own food using sunlight (like plants). Grass is a plant and uses photosynthesis to make food. The mouse and owl are consumers — they eat other organisms.

3. What is the predator in this food chain?

✔ Answer: owl

A predator is an animal that hunts and eats other animals. In this food chain:
- Grass → Mouse → Owl
- The owl eats the mouse, so it is the predator.

4. Here is a food chain that is in the wrong order. Write the names in the right order in the spaces below.

Organisms shown:
- eagle
- plant
- caterpillar
- small bird

We need to arrange them in the correct food chain order.

Step-by-step reasoning:
- Plant is a producer → makes its own food.
- Caterpillar eats the plant → primary consumer.
- Small bird eats the caterpillar → secondary consumer.
- Eagle eats the small bird → top predator.

So the correct order is:

👉 plant → caterpillar → small bird → eagle

Now fill in the blanks:

```
plant → caterpillar → small bird → eagle
```

One of these organisms is both a predator and prey. Which one is it?

✔ Answer: small bird

Explanation:
- The small bird eats the caterpillar → so it is a predator.
- But the eagle eats the small bird → so the small bird is also prey.
- Therefore, the small bird is both a predator and prey.

✔ Final Answers:

1. is eaten by
2. grass
3. owl
4. plant → caterpillar → small bird → eagle
- Organism that is both predator and prey: small bird
