Indicator Species: Any biological species that defines a trait or characteristic of the environment.

Ecological Succession: A process in which the communities of an ecosystem change over time.

Primary Succession: The gradual growth of organisms in an area that was previously bare.

Secondary Succession: The series of community changes which take place on a previously colonized, but disturbed or damaged habitat.

Pioneer Species: Species which colonize previously uncolonized land, usually leading to ecological succession.

Climax Community: A stable community of a diverse number of species.

Limiting Factors: Factors that prevent a population from reaching carrying capacity.

Carrying Capacity: The number of individuals of a species that an ecosystem can support.

Population Growth: An increase in the number of people who inhabit a territory.

Population Growth Rate: The rate at which the number of an organism increases in a territory.

Expontential Growth: Occurs when some quantity regularly increases by a fixed percentage.

J-Curve: Shows a steady population, then shoots up, representing a fast increase in population.

S-Curve: Its exponential growth has a steady start to begin with, then quickly increases, and then finally levels off.
