Choose two ecosystems, a marine and a terrestrial ecosystem. Create biomass and energy pyramids for each ecosystem. Then, study and compare each pyramid in terms of production efficiency and productivity. Focus on the following points when working on this activity.

The difference between the pyramids in each ecosystem.
The efficiency with which energy is transferred through all the trophic levels in the Energy and Biomass pyramids.
Explain how each level is a biomass to the next level in both pyramids.
Use the following keywords when researching: primary productivity, efficiency, production, biomass pyramids, and productivity pyramids.
