1. Aim:How does energy travel through an ecosystem?

2. Food Chain Rose plant  aphids  beetle  chameleon  hawk The deep-sea hydrothermal ecosystems are the exception to this food (no photosynthesis, instead chemosynthesis)

3. Food Web

4. Section 3-2 Salt Marsh Ecosystem Food Web

5. Energy flow in an ecosystem can be illustrated using ecological pyramids. Numbers pyramid Biomass pyramid Energy Pyramid

6. Number Pyramid Shows numbers but not size

7. Biomass Pyramid Indicates the Total mass of the organisms in each trophic level

8. Energy Pyramid Shows the total Amount of energy present in each level.
