Interactive food chain worksheet for children, teaching the flow of energy in an ecosystem with fun illustrations and numbered steps.

This is a food chain worksheet designed for kids to learn about the flow of energy in an ecosystem. The goal is to number the organisms in the correct order of the food chain, starting from the producer (which makes its own food) to the top consumer (which eats other animals).

🌞 Step-by-step Explanation:

Let’s look at the images and understand their roles in the food chain:

1. Sun – Provides energy for plants to make food through photosynthesis.
2. Grass – A plant that uses sunlight to produce its own food. It's a producer.
3. Grasshopper – Eats grass. It's a primary consumer (herbivore).
4. Mouse – Eats grass or seeds. Also a primary consumer, but can be eaten by predators.
5. Snake – Eats mice. It's a secondary consumer (carnivore).
6. Hawk – Eats snakes (and possibly mice). It's a tertiary consumer or top predator.

🔄 Food Chain Order:

The correct flow of energy is:

Sun → Grass → Grasshopper → Mouse → Snake → Hawk

But note: The Sun is not part of the food chain itself — it provides energy, but isn't consumed. So we start with grass as the first living organism in the chain.

So the correct sequence of organisms (from bottom to top) is:

1. Grass
2. Grasshopper
3. Mouse
4. Snake
5. Hawk

Wait — but there are six boxes, and six numbers (1 to 6). Let’s match them carefully.

Looking at the image layout:

- Top row: Grass, Hawk, Sun
- Bottom row: Grasshopper, Mouse, Snake

We need to assign numbers 1 to 6 to each box based on the order of the food chain.

✔ Correct Numbering:

Let’s assign the numbers in the order of energy flow:

1. Grass – Producer (starts the chain) → Box under Grass
2. Grasshopper – Eats grass → Box under Grasshopper
3. Mouse – Eats grass or insects → Box under Mouse
4. Snake – Eats mouse → Box under Snake
5. Hawk – Eats snake → Box under Hawk
6. Sun – Not eaten, but provides energy → This goes last, because it's the source of energy, but not consumed.

> ⚠️ Important: In food chains, the Sun is placed at the beginning, but since it's not consumed, sometimes it's shown separately. However, in this worksheet, since it's included and has a blank below it, we must assign it a number.

But logically, the Sun comes before everything else — so it should be #1?

But wait — the grass uses the sun to grow. So:

- Sun → Grass → Grasshopper → Mouse → Snake → Hawk

So the correct order is:

1. Sun (energy source)
2. Grass (producer)
3. Grasshopper (primary consumer)
4. Mouse (primary/secondary consumer)
5. Snake (secondary consumer)
6. Hawk (top predator)

✔ That matches the flow of energy.

Now, let’s map the positions:

- Top row:
- Left: Grass → should be #2
- Middle: Hawk → should be #6
- Right: Sun → should be #1

- Bottom row:
- Left: Grasshopper → #3
- Middle: Mouse → #4
- Right: Snake → #5

✔ Final Answer:

Fill in the blanks like this:

Top Row (left to right):
- Grass → 2
- Hawk → 6
- Sun → 1

Bottom Row (left to right):
- Grasshopper → 3
- Mouse → 4
- Snake → 5

🔢 Box Numbers:

| Image | Number |
|-------------|--------|
| Sun | 1 |
| Grass | 2 |
| Grasshopper | 3 |
| Mouse | 4 |
| Snake | 5 |
| Hawk | 6 |

🎯 Summary:

This worksheet teaches children the order of a food chain:

> Sun → Grass → Grasshopper → Mouse → Snake → Hawk

By numbering the boxes correctly, kids learn how energy flows from the sun to producers and then through consumers.

✔ Answer:
- Sun → 1
- Grass → 2
- Grasshopper → 3
- Mouse → 4
- Snake → 5
- Hawk → 6

Place these numbers in the corresponding boxes below each image.
