Ecosystem Review: Who Needs Who?

Week 18 • Friday • Life Science

📖 Reading Time

This week we learned about ecosystems. An ecosystem is a habitat plus all its living and non-living parts. Plants are producers. They make their own food using sunlight. Animals are consumers. They eat plants or other animals.

Everything in an ecosystem is connected, like a big web. The grass needs sun, soil, and rain. The rabbit needs the grass. The fox needs the rabbit. If one part changes, all the parts feel it.

You even built a tiny ecosystem in a jar! Your terrarium shows how plants, soil, water, air, and light all work together.

✏️ Review Questions

1. What two kinds of parts make up an ecosystem?

2. What do producers do?

3. What do consumers do?

4. Name the parts of your terrarium ecosystem.

🧠 What Happens If...?

1. What happens to the rabbits if all the grass dies?
