Ecosystem
The living organisms in a particular place, together with their physical environment.

Community
All of the groups of animals or plants living together in a environment interacting with one another.

Detritivores
Organisms that obtain nutrients by consuming decomposing plant and animal parts as well as organic ***** matter.
4 of 20
Decomposer(s)
(An) organism(s) that decomposes organic material.
5 of 20
Producers
The first level in a food pyramid; consist of organisms that generate the food used by all other organisms. Includes plants (photosynthesis).

Herbivores
An animal that feeds primarily on plants.
7 of 20

Gross primary productivity (GPP)
The rate at which the producers of an ecosystem capture and store energy as biomass.
