Ecology Flashcards
Energy Pyramid
A model that shows the available amount of energy in each trophic layer of an ecosystem.
Decomposer
Organisms which carry out the process of decomposition by breaking down dead or decaying organisms.
Food Web
A model that shows many different feeding realationships among living things.
Coniferous
