Keep in mind the importance of energy flow in an ecological community – energy only flows in via the producers. Their energy absorption creates an absolute limit on how much life can be supported. Each trophic level gets only 10% of the energy from the previous trophic level. The amount of food energy decreases at each trophic level. That idea is represented visually in a pyramid of numbers or pyramid of biomass.

Here are the notes:

Complete the cell anatomy assignment and you will be one step closer to understanding the secrets of life.
