What can affect the carrying capacity of a habitat?

The carrying capacity of a habitat refers to the maximum number of individuals of a particular species that an environment can sustain over time without degrading the habitat. This capacity is influenced by a variety of factors, both natural and anthropogenic.

Human influences, such as urban development, agriculture, hunting, and pollution, can significantly reduce the resources available in a habitat, thereby lowering its carrying capacity. For example, deforestation for agricultural purposes removes essential habitats and food sources for many species.

On the other hand, natural events, including wildfires, floods, droughts, and disease outbreaks, can also dramatically impact the carrying capacity. These events can destroy habitats, reduce food availability, and increase mortality rates among species, leading to a decrease in the overall population a habitat can sustain.

Additionally, seasonal weather changes can affect food availability and breeding cycles, but they are part of the broader natural influences that can alter carrying capacity. Therefore, both human and natural factors play crucial roles in determining the carrying capacity of a habitat, making the option that includes both nature and humans the most comprehensive and accurate choice.
