Which factor would likely increase the carrying capacity of an environment for a species?

Increasing the availability of food and shelter is a key factor that can enhance the carrying capacity of an environment for a species. Carrying capacity refers to the maximum number of individuals of a particular species that an environment can sustainably support over time, based on the availability of resources.

When food supplies are abundant, animals have sufficient energy for growth, reproduction, and overall survival. Similarly, increased shelter availability provides crucial protection from predators and harsh environmental conditions, allowing a greater number of individuals to thrive. This combination of adequate food and shelter creates an environment where more individuals can survive and reproduce, directly contributing to a higher carrying capacity.

In contrast, increased competition for resources generally leads to a decrease in population size, as not all individuals may secure enough resources to survive. The introduction of a new predator would likely reduce the population of the prey species, thus lowering the carrying capacity. Extreme weather conditions can also negatively impact the environment's ability to support life, reducing the availability of food and shelter.
