Carrying capacity (K) in logistic growth represents:

RankGuru · Accepted Answer

1. **Population Growth Types**: Exponential ($J$-shaped) and Logistic ($S$-shaped).
2. **Logistic Growth**: Real-world populations face resource limits (food, space, predators).
3. **Carrying Capacity ($K$)**: The maximum number of individuals of a population that a particular environment can **support and sustain** indefinitely without degrading the resource base.
4. **Mechanism**: As the population size ($N$) approaches $K$, the growth rate slows down until it reaches zero ($dN/dt = 0$) when $N = K$.
