ECOLOGICAL PYRAMIDS A diagram that shows relative amounts of energy or matter within each trophic level. 3 Types: Energy Pyramid Biomass Pyramid Pyramid of Numbers

Energy Pyramid REMEMBER: About a 90% energy loss between trophic levels Energy Pyramid At every trophic level energy is lost as heat or through life processes Available energy decreases at each level 10% rule – each trophic level passes only about 10% of the energy of the one below it Higher on food chain, more area needed to live. This pyramid exists in every ecosystem.

Pyramid of Numbers Not all pyramids of #s look like this! Some have small base Like a tree ecosystem

Biomass Pyramids Displays the biomass (living tissue) at each trophic level.
