Energy Flow

5. Energy Pyramids

5.1 Trophic Levels, Producers, consumers, decomposers

Explore Energy Pyramids: Producers, Consumers & Decomposers

You will discover how energy moves through living things from plants that make their own food all the way to animals at the top of the pyramid.

What You'll Learn

You learn that producers make food using sunlight through photosynthesis.

You discover consumers must eat other organisms to get their energy.

You find that decomposers recycle nutrients back into the soil always.

You see energy decreases as it moves up each trophic level.

What You'll Practice

You will identify producers, consumers, and decomposers in food chains.

You will explain how energy flows upward through each trophic level.

You will practice placing organisms correctly on an energy pyramid diagram.

Why This Matters

Understanding how energy flows through producers, consumers, and decomposers helps you see how every living thing in nature depends on another to survive.
