What distinguishes population ecology from community ecology?

Population ecology is primarily concerned with the dynamics of individual species within a specific population, emphasizing factors such as birth rates, death rates, and population growth. It seeks to understand how these aspects affect the population's size, structure, and interactions with the environment. In contrast, community ecology focuses on the interactions between different species within a community, examining how species coexist, compete, and affect one another.

The distinction between these two branches lies in their scope: population ecology narrows in on a single species and its characteristics and behaviors, while community ecology broadens the perspective to include multiple species and their interactions. Understanding this difference is crucial for studying ecological systems, as the dynamics of one species can significantly influence a community, and vice versa.
