Educational food chain worksheet for kids, illustrating how energy flows through ecosystems with animal and plant images.

Let's solve this Food Chains worksheet step by step.

🔍 Understanding the Concept

A food chain shows how energy flows from one organism to another. Energy starts with producers (like plants), which make their own food using sunlight. Then, consumers (animals) eat the producers or other consumers.

The correct flow of energy is:
> Producer → Primary Consumer → Secondary Consumer

---

Now let’s analyze each option:

---

✔ Option 1:

Grass → Grasshopper → Frog

- Grass: Producer (makes its own food)
- Grasshopper: Eats grass → primary consumer
- Frog: Eats grasshoppers → secondary consumer

✔ This is a correct food chain.

✘ Option 2:

Fish → Seaweed → Shark

- Seaweed: Producer (plant-like, makes its own food)
- Fish: Could eat seaweed, but here it’s shown *before* seaweed — that would mean the fish eats seaweed, but then seaweed eats shark? That doesn’t make sense.
- Shark: Eats fish, not seaweed.

But in this order:
Fish → Seaweed → Shark
This implies: Fish eats seaweed → Seaweed eats shark → Wrong!

Seaweed can't eat sharks. Also, fish don’t usually eat seaweed in this context (though some do, but the direction is wrong).

✘ Incorrect flow – energy cannot go from fish to seaweed.

✘ Option 3:

Bird → Mouse → Owl

- Bird: Might eat mice, but here it's shown as eating mouse? Wait — no!
- The arrow goes: Bird → Mouse → Owl
- So, bird eats mouse → mouse eats owl? That’s impossible!

Wait — actually, birds often eat mice, so if the bird is the predator and the mouse is prey, the chain should be:
> Mouse → Bird → Owl

But here it's written:
> Bird → Mouse → Owl

That means: Bird eats mouse → Mouse eats owl → Impossible!

So, this sequence is backwards.

✘ Incorrect.

✘ Option 4:

Acorns → Squirrel → Hawk

- Acorns: Part of a tree — producer (seed/nut)
- Squirrel: Eats acorns → primary consumer
- Hawk: Eats squirrels → secondary consumer

✔ This is a correct food chain.

✔️ Check this box

✔ Final Answer:

Check the boxes for:
- Option 1: Grass → Grasshopper → Frog
- Option 4: Acorns → Squirrel → Hawk

---

🟩 Correct Choices:

✔ First and ✔ Fourth food chains are correct.

---

✔ Summary:

- ✔️ Grass → Grasshopper → Frog
- ✘ Fish → Seaweed → Shark
- ✘ Bird → Mouse → Owl
- ✔️ Acorns → Squirrel → Hawk

👉 Answer: Check the first and fourth boxes.
