The term for the study of interactions between species is called synecology. This field examines how different species coexist, compete, and interact within a particular ecosystem. Synecology focuses on understanding the relationships between organisms, such as predator-prey dynamics, mutualism, and competition for resources. Studying these interactions helps ecologists ascertain how communities function, how species adapt to environmental changes, and the overall health of an ecosystem. By exploring these interspecies relationships, researchers can draw conclusions about biodiversity, resilience, and the impacts of human activity on natural ecosystems.
