What happens when a limiting factor improves?

When a limiting factor improves, it typically allows for greater availability of essential resources that a population relies on, such as food, water, or habitat space. As these resources become more accessible or abundant, the carrying capacity of the environment for that particular species increases.

This can lead to higher rates of survival and reproduction, facilitating population growth. The improvement in limiting factors means that more individuals can find the resources they need to thrive, ultimately allowing the population to grow larger. Over time, this growth can stabilize until the population reaches a new balance with the environment.

In summary, the increase in the availability of resources due to the improvement of a limiting factor directly supports population growth, making it the most accurate answer in this context.
