The role a species plays in the community is called its

• ecology

• abiotic role

• ecological niche

• habitat

• biotic role

Ecology is best defined as the study of

• the rate of population changes

• organisms as they interact with other organisms and with their physical surroundings

• communities

• populations

• how populations are restricted by environmental resistance

An ecosystem contains

• only the biotic (living) components of the environment

• only the energy flow components of an environment

• both the living organisms and the abiotic components of the environment

• only the abiotic (nonliving) components of the environment
