Ecosystem and Food Chains

Introduction

Imagine a world where all living things are connected in a delicate balance.

You are about to become an ecosystem investigator! Your mission is to find out how plants, animals, and humans depend on each other to survive. After this activity, you will be able to explain how energy moves in nature and why it is important to protect nature.

Task

Your task is to design a Food Chain Poster or Digital Presentation that will show:

At least one complete food chain

The role of producers, consumers, and decomposers

The flow of energy within the ecosystem

A brief description of each part

Final Output:

A poster or a Powerpoint/Canva presentation

A 3-5 minute explanation on your work

Process

Follow these steps:

Step 1: Learn the Basics

Learn the definition of an ecosystem
Learn the definitions of producers, consumers, and decomposers

Step 2: Explore Food Chains

Learn how the food chain gets its energy
Learn from real-life examples

Step 3: Choose Your Ecosystem

Choose one of these:

Forest
Ocean
Grassland

Step 4: Create Your Output

Design your food chain
Make sure to label your work properly
Add explanations for your work

Step 5: Present Your Work

Tell the class about your food chain
Tell the class how organisms interact with each other

Conclusion

Great job, Ecosystem Investigator!

You have learned about the connections between living things by exploring the world of food chains. Here is something to think about:

What would happen if one organism in a food chain goes away?

Learning about ecosystems is important to preserve our environment.
