The Parts of Ecosystems Plants originate, live, and die in  communities  consisting of plants and a variety of other organisms,  large and small. All the living constituents make up the  biota  (or the biotic component) of the  community. The nonliving, physical factors (such as temperature, light, and nutrients) that affect the  life of organisms—and determine to a large extent the kinds of organisms present—collectively  represent the  abiotic  factors of the community. The  environment  is the total of all the biotic and  abiotic forces in which an organism or a community of organisms lives.  The biotic components and abiotic portions of the environment are inseparably intertwined and  constantly exchange materials; there are  inputs  (materials or organisms entering) and  outputs  (materials or organisms leaving) to the community;  energy  flows one way  through
