Basic Food Chain worksheet for teaching students about ecosystems and consumer roles.

Let's solve this Basic Food Chain worksheet step by step.

🔍 Step 1: Understand the Picture

The image shows:

- Sun (energy source)
- Grass (on the ground)
- Rabbit (eating grass)
- Fox (predator)
- Owl (flying above, also a predator)

---

🌿 Step 2: Identify the Roles in the Food Chain

In a food chain:
- Primary Producer: Makes its own food (usually plants using sunlight).
- Primary Consumer: Eats producers (herbivores).
- Secondary Consumer: Eats primary consumers (carnivores or omnivores).
- Tertiary Consumer: Eats secondary consumers (top predator).

✔ Answering the Questions

#### 1. Primary Producer
- The grass is the primary producer.
- It uses sunlight (from the sun) to make food via photosynthesis.
> ✔ Answer: Grass

#### 2. Primary Consumer
- The rabbit eats grass → herbivore → primary consumer.
> ✔ Answer: Rabbit

#### 3. Secondary Consumer
- The fox eats the rabbit → carnivore that eats a primary consumer.
> ✔ Answer: Fox

#### 4. Tertiary Consumer
- The owl eats the fox (or could eat rabbits too, but in this case, it’s shown as higher up).
- Since the owl is shown above the fox and likely preys on animals like the fox or rabbit, it acts as a tertiary consumer here.
> ✔ Answer: Owl

🔄 Draw Arrows for the Food Chain

Now, draw arrows to show energy flow (from eaten to eater):

```
Sun → Grass → Rabbit → Fox → Owl
```

So, arrows should be drawn like this:

- From sun to grass (sun provides energy)
- From grass to rabbit (rabbit eats grass)
- From rabbit to fox (fox eats rabbit)
- From fox to owl (owl eats fox)

> ⚠️ Note: The sun is not consumed directly — it's an energy source. So we draw an arrow from sun to grass to show energy transfer.

✔ Final Answers to Fill In:

1. Primary Producer: Grass
2. Primary Consumer: Rabbit
3. Secondary Consumer: Fox
4. Tertiary Consumer: Owl

📝 Summary

This is a simple terrestrial food chain:

> Sun → Grass → Rabbit → Fox → Owl

Each organism depends on the one before it for energy.
