Ecophysiology is a branch of biology that deals with the physiological processes of organisms in relation to their environments. It focuses on how organisms adapt and respond to various environmental factors, such as temperature, light, moisture, and nutrients. Ecophysiology seeks to understand how these environmental factors influence the growth, development, reproduction, and survival of organisms. Researchers in this field study the physiological mechanisms that allow organisms to thrive in different environments and how they interact with other organisms in their ecosystems. Overall, ecophysiology helps us better understand the complex relationships between organisms and their environments.
