carrying capacity - the maximum number of individuals of a particular species that a particular environment can support
demography - the scientific study of human populations
pollutants - a harmful material that can enter the biosphere

Review “Wolf and Moose Populations on Isle Royale” line graph in notes - When the wolf population starts to decline, the moose population increases. The moose population also rapidly declined because of overcrowding and the increase of the wolf population. 

Describe factors that keep a population from growing further once its carrying capacity is reached. - food and water supply, habitat space, and competition with other species are all things that keep a population at its carrying capacity

Differentiate between renewable and nonrenewable resources.
- Renewable resources have the ability to naturally replenish themselves like trees and falling water. Nonrenewable resources can not be replaced naturally, coal and natural gas are examples. 

Describe what will happen if a population exceeds carrying capacity.
- If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive.

Identify factors that affect population growth.
- birth rate, death rate, emigration, immigration
