The Zone of Life Outline of a man and his imprint on the land, the ocean, and the atmosphere What is the “zone of life,” or biosphere? According to NASA, it is “the portion of Earth and its atmosphere that can support life.” Like the shell of an egg, the biosphere is a very thin layer, or zone, that encompasses our planet. The biosphere consists of living things and the environment—the atmosphere, the land, and the oceans—from which they derive the energy and nutrients needed for life. For instance, plants capture solar energy and use it to convert carbon dioxide, water, and minerals into oxygen and food. Humans and animals take in oxygen and food and return carbon dioxide and other matter to the system. And the cycle repeats itself. Thus, the biosphere can sustain life indefinitely. assets.jw.org/assets/m/w14/20140901/w14_20140901.art/2014642_univ_cnt_4_xl.jpg
