Ecophysiology is the study of how living things adapt to different environments. It looks at how plants or animals use their energy to survive and thrive in different climates or habitats. For example, a plant in a hot desert may have to use a different strategy to survive than one living in a cold mountain range. Scientists want to understand how plants and animals are able to cope with extreme temperatures, lack of water, and other challenges in their environment. By understanding how animals and plants use their energy to survive, we can better protect them and make sure their populations stay healthy.
