Ecological pyramid
A graph represents trophic level numbers within an ecosystem. The primary producer level is at the base of the pyramid with the consumer levels above
-
Numbers pyramid
Compares the number of individuals in each trophic level
-
Biomass pyramid
Compares the total dry weight of the organisms in each trophic level
-
Energy pyramid
Compares the total amount of energy available in each trophic level. This energy is usually measured in kilocalories
