Which scientific concept relates to the study of interactions between organisms and their environments?

The study of interactions between organisms and their environments is known as ecology. This branch of biology focuses on understanding how living organisms, including humans, animals, and plants, interact with each other and with their physical surroundings, such as climate, soil, water, and other environmental factors. Ecologists examine these relationships to understand the dynamics of ecosystems, population distributions, and the impacts of environmental changes on living organisms.

In contrast, evolution pertains to the processes that lead to changes in species over time, primarily through natural selection and genetic variation. Physiology deals with the functions and mechanisms occurring within organisms, studying how biological systems operate. Anatomy focuses on the structure of organisms and their parts. While all these areas are interconnected in biological sciences, ecology specifically addresses the interactions between organisms and their environments, making it the correct choice for this question.
