Abiotic: non-living

Biotic: living

Carrying Capacity: the maximum population an ecosystem can support of a given species.

Competition: for food and resources Competition: for food and resources. Types: interference (by direct attack), exploitation (forced to share a resource), scramble (everyone gets something), contest (one competitor gets it all), and restrictive (preventing someone else from getting it).

Exponential Growth: Increase in number or size, at a constantly growing rate.

Limiting Factors : Any factor (biotic or abiotic) that inhibits the growth of a species population.

Logistic population growth: occurs when the growth rate decreases as the population reaches carrying capacity. Carrying capacity is the maximum number of individuals in a population that the environment can support.

Overpopulation: occurs when a population of a species exceeds the carrying capacity of its ecological niche.

Population: Organisms inhabiting a territory.

Scale: Levels of organization between organisms in the biosphere (Ex Scale: Levels of organization between organisms in the biosphere (Ex. BECPO- What do these initials represent?)
