Answer to Question #258428 in Ecology for Josh

Question

What is population ecology and why is it easier to study plant population than animal

population? Explain why populations cannot continue to increase indefinitely?

Answer 1

Population ecology is the study of these and other questions about what factors affect population and how and why a population changes over time. The study of population ecology includes understanding, explaining, and predicting species distributions.

Populations cannot grow exponentially indefinitely. Exploding populations always reach a size limit imposed by the shortage of one or more factors such as water, space, and nutrients or by adverse conditions such as disease, drought and temperature extremes.
