essential question: how are population size influenced and controlled within natural environment?

Brief Explanations:

Population size in natural environments is influenced by factors like birth - death rates, availability of resources (food, water, shelter), presence of predators, and disease. Limiting factors such as carrying capacity control population growth. For example, when resources are abundant, populations may grow, but as they approach the environment's carrying capacity, growth slows due to increased competition for resources.

Answer:

Population size in natural environments is influenced by birth - death rates, resource availability, predators, and disease, and is controlled by factors like carrying capacity.
