Exploring Population Dynamics and Limiting Factors

The video tutorial explains how populations grow exponentially when conditions are ideal, but in the wild, growth is limited by factors such as severe weather, predators, disease, and competition for resources. These limiting factors are related to the concept of carrying capacity, which is the maximum number of individuals a habitat can support. The tutorial uses graphs to illustrate these concepts, comparing population growth to a sponge's capacity to absorb water.

What happens to individuals in a population as they get older and remain healthy?

• They stop reproducing.

• They become predators.

• They reproduce and have offspring.

• They migrate to other areas.
