Food Webs and Energy Pyramids Lesson

Food chains show ONE path of energy through an ecosystem. The arrow shows the flow of energy from one organism to another OR who eats who.

​

Food Chains

Food webs are MULTIPLE food chains put together. It shows ALL paths of energy in an ecosystem OR all of what each organism eats.

Producers- Create their own food
Consumers- Eat other things for food

Energy pyramids show the amount of energy available to each trophic level.

Trophic means energy. Energy decreases as you go up the pyramid.
