An ecosyst! em is a community of different species interacting with each other and with their nonliving environment of matter and energy. tout supporting players of the earths diverse ecosystems comprise the biosphere. 4-2The Earths Life-Support Systems Various interconnected spherical layers make up the earths life-support system. The atmosphere is the thin tissue layer of air around the planet. The troposphere is the air layer about 11 miles above sea...If you want to get a full essay, discriminate it on our website: OrderCustomPaper.com
