Ecology and ecosystems

No living thing exists in isolation. It interacts with other living things and with its physical surroundings. The study of these relationships is called ecology. Ecologists consider all the organisms that live in one area as as inter-dependent community. All plants and animals rely on , and influence, vital factors in their environment, such as the supply of nutrients, food, and water. A community and its environment is called an ecosystem.
