What does the term 'environment' refer to in biology?

The term 'environment' in biology encompasses all the external conditions and influences that affect the life of an organism. This includes not only physical surroundings such as air, water, soil, and climate but also the other living organisms that interact with that organism, such as predators, prey, competitors, and symbionts. This broader definition allows us to understand how organisms are shaped by and respond to a complex web of interactions within their surroundings.

In biological studies, considering the environment as the complete set of surroundings is essential for grasping concepts related to ecology, adaptation, and survival strategies of different species. Recognizing the environment in this holistic way helps appreciate the interconnectedness of life and the many factors that can influence living organisms.
