1. Abiotic: non-living

2. Biotic: living

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

4. 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).

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

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

7. 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.

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

9. Population: Organisms inhabiting a territory.

10. 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?)
