diagram the flow of energy within trophic levels and describe how the available energy decreases in successive trophic levels in energy pyramids;

diagram the flow of energy within trophic levels and describe how the available energy decreases in successive trophic levels in energy pyramids;

Please watch BOTH videos. They contain dfferent content and you must know both.

Use the following interactive website to practice identifying the pieces of a food chain.
