a self feeder; and organism that goes through photosynthesis to make its own food. |
|
Heterotroph |
an other feeder; an organism that must consume others for food. |
|
biodiversity |
the variety of organisms in a given area, the genetic variation within a population, the variety of species in a community, or the variety of comm. in an ecosystem. |
|
succession |
the replacement of one type of community by another at a single location over a period of time. |
