True or False: The movement of matter through the living and non-living parts of an ecosystem is a continuous cycle.
True. Matter in an ecosystem may change form, but it never leaves the ecosystem.

False: Producers are a source for other organisms.
True or False: Changes in the environmental conditions does not affect the survival of both individuals and entire species.

What limits the exponential growth of a population?
Resources (competition for food, water), Predation (predator and prey relationships), environmental factors, and disease.
The part of Earth and the atmosphere in which living things exist.
