Study Notes
Population Growth and Capacity
- Carrying capacity: the maximum number of individuals an environment can support.
Logistic Growth
- Growth rate (r) depends on resource availability and intrinsic factors such as reproduction rate and mortality rate.
- A growth rate of 1 indicates the population is neither growing nor declining.
- After a population reaches its carrying capacity, the growth rate decreases and the population stabilizes.
- N represents the current population size in logistic growth.
