Food chain worksheet for Year 4 Science, featuring three illustrated food chains and questions to identify producers, consumers, and predator-prey relationships.

Let’s go step by step through each question.

---

1. Name the producer in each food chain:

Producers are plants or organisms that make their own food (usually using sunlight). In these chains, they’re always at the start.

a) First chain: The flowers → Flowers
b) Second chain: The grass → Grass
c) Third chain: The tree → Tree

✔ So:
a) Flowers
b) Grass
c) Tree

---

2. Name the first consumer in each food chain:

First consumers eat the producers. They’re the next animal after the plant.

a) Butterfly eats flowers → Butterfly
b) Shrimp eats grass? Wait — actually, shrimp usually live in water and don’t eat grass. But in this diagram, it shows grass → shrimp → mouse → owl. So we follow what’s drawn: Shrimp is shown eating grass here (even if not realistic, for the worksheet we go with the diagram).
c) Deer eats tree leaves → Deer

✔ So:
a) Butterfly
b) Shrimp
c) Deer

*(Note: In real life, shrimp don’t eat grass — but since this is a simplified school diagram, we answer based on what’s shown.)*

3. What animal eats the frog?

Look at the first chain:
Flowers → Butterfly → Frog → Snake

So the snake eats the frog.

✔ Answer: Snake

---

4. The deer is prey for the lion. Is this true or false?

In the third chain:
Tree → Deer → Lion

The lion eats the deer → so yes, the deer is prey for the lion.

✔ Answer: True

5. What animal eats the caterpillar?

Wait — there’s no “caterpillar” in the diagrams! Let’s check again.

Actually, looking back — maybe you meant “butterfly”? Or perhaps it’s a trick?

Hold on — in the first chain, it’s:

Flowers → Butterfly → Frog → Snake

There’s no caterpillar shown. But sometimes butterflies come from caterpillars… however, in this diagram, it says “butterfly”, not “caterpillar”.

BUT — let’s read carefully: Question 5 says “What animal eats the caterpillar?”

Since “caterpillar” isn’t in any of the chains as written, perhaps it’s a mistake? Or maybe they mean the butterfly stage?

Wait — look again at the image description: The first chain has a butterfly. Maybe the worksheet meant to say “butterfly”? Or perhaps in some versions it’s a caterpillar?

Actually — rechecking your original problem text: You wrote “caterpillar” in question 5.

But in the image provided (as described), it’s a butterfly, not a caterpillar.

This might be an error in the question — OR — perhaps in the actual printed version, it’s a caterpillar? Since I can’t see the image, I must rely on your text.

You said: “Identify the different parts of a food chain” and listed:

Chain 1: Flowers → Butterfly → Frog → Snake

So if the question says “caterpillar”, but the diagram shows “butterfly”, then either:

- It’s a typo, and they meant butterfly → then frog eats it.
- Or, if it really is caterpillar, then maybe the butterfly was supposed to be caterpillar? That would make more sense biologically — because frogs eat caterpillars, not usually adult butterflies.

Given that, and since this is Year 4 science, it’s likely they meant caterpillar instead of butterfly — because caterpillars are commonly eaten by frogs.

So assuming that’s the case (and it’s a common mix-up in worksheets):

If the first link after flowers is caterpillar, then frog eats it.

✔ Answer: Frog

*(We’ll go with this — because otherwise the question doesn’t match the diagram. Probably a labeling error in the worksheet.)*

6. What animal does the owl eat?

Second chain:
Grass → Shrimp → Mouse → Owl

So the owl eats the mouse.

✔ Answer: Mouse

Now let’s compile all answers clearly.
