Basic Food Chain worksheet for students to learn about ecosystem relationships.

Let’s think about how food chains work.

In a food chain, energy moves from one living thing to another. It always starts with the sun — because plants need sunlight to grow. Then:

- The primary producer is usually a plant (like grass) that makes its own food using sunlight.
- The primary consumer eats the plant — like a rabbit eating grass.
- The secondary consumer eats the primary consumer — like a fox eating a rabbit.
- The tertiary consumer eats the secondary consumer — like an owl eating a fox.

Now let’s match this to the pictures in your worksheet:

1. The sun gives energy to the grass → so grass is the primary producer.
2. The rabbit eats the grass → so rabbit is the primary consumer.
3. The fox eats the rabbit → so fox is the secondary consumer.
4. The owl eats the fox → so owl is the tertiary consumer.

You can draw arrows like this:
Sun → Grass → Rabbit → Fox → Owl

But since the question asks you to write or draw each part in the boxes, here’s what goes in each box:

---

Final Answer:
Primary producer: Grass
Primary consumer: Rabbit
Secondary consumer: Fox
Tertiary consumer: Owl
