Carrying Capacity

This is the approximate number of individuals that can be supported by

the environment. This value fluctuates with changes in temperature, moisture

and resources that are available.

Climate

This describes the pattern of annual temperature and precipitation for a

given area. This will often determine how much life can be supported by any

given environment.

Population

This describes the number of individuals living in a particular place

during a particular period of time.

R - StrategistThis describes a style of living that

produces a large number of offspring with low survival rate, short life span,
