Ecosystem Matter and Energy Flow
Learning Objective
I can describe how matter and energy move through an ecosystem.
Key Concepts
In a food chain, the flow of energy and matter through a community can be easily understood.
Producers, like green plants and microorganisms, convert the sun's energy into food energy through the process of photosynthesis.
Only about 10 percent of the chemical energy consumed by an organism passes on to the next level in a food chain, which is known as the "10 percent rule".
