How Does Energy Flow Through An Ecosystem
Food chains and food webs deal with both matter and energy. When ecologists want to focus only on energy, they use another type of model--an ecological pyramid.
Pyramids of Biology
Pyramid Changes By Trophic Level
As you go up the energy pyramid less and less energy is available.
As you go up the numbers pyramid the population is less and less.
As you go up the biomass pyramid the weight less and less.
As you go up the numbers pyramid the population is less and less.
As you go up the biomass pyramid the weight less and less.
