|---|
| Resource | is necessary for life and might include food, water, space, and light |
| Carrying capacity | largest number of individuals in a species that an environment can support long-term |
| Limiting factor | biotic or abiotic factor that restricts the number, distribution, or reproduction of a population within a community |
| Predator | the organism that pursues another organism for foood |
| Prey | the organism to be used for food that is pursued by another organism |
| Competition | occurs when more than one organism uses a resource at the same time |
| Density dependent factors | environmental factor, such as predation, disease, and competition, that depends on the number of members in a population per unit area |
| Density independent factors | environmental factor, such as storms and extreme heat or cold, that affects populations regardless of their density |
| Exponential population growth | occurs when populations grow exponentially until some limiting factor slows the population's growth |
| Logistical population growth | occurs when the population's growth slows or stops following exponential growth, at the population's carrying capacity. |
| predation | the act of one organism consuming another organism for food |
