The study of environment is known as ecology. Ecology is a branch of science that studies the interactions between organisms and their environment, including the physical, chemical, and biological components of the environment. It also looks at how these interactions affect the distribution and abundance of organisms, as well as the flow of energy and matter through ecosystems. Ecology is an important field of study, as it helps us to understand the complex relationships between organisms and their environment, and how human activities can impact the environment.
