three types of biodiversity are what _____
genetic, species, and ecosystem diversity
Model of an ecosystem that shows how energy is distributed throughout an ecosystem as well as the relative amount of organisms in each trophic level.
Food Pyramid
Species compete against one another for survival (food, land, shelter, mates)
