생태계(Ecosystem)?


#1
The ecosystem is a mix of the words ecological and system. Ecosystem refers to all the natural things and processes that control the behavior of plants, animals, and minerals in a certain part of nature. (One example is the desert ecosystem. It is usually hot and dry in the desert though it can be very cold at night. Therefore, all of the plants, animals, and other things have adapted to this environment.) (In other words, there is a harmony in the desert ecosystem between all things that live or exist there and the environment.) There is no limit as to how big or how small an ecosystem may be. As long as the harmony is real, then there is an ecosystem.
