Key Ideas Life on earth is sustained by the flow of energy from the sun, the cycling of matter or key nutrients through the biosphere, and gravity that keeps the molecules in the atmosphere from flying off into space. Some organisms produce food; others consume food. The biodiversity found in the earth’s genes, species, ecosystems, and ecosystem processes is a vital renewable resource.

Key Ideas Continued Soil supplies most of the nutrients needed for plant growth, helps purify water, and stores carbon that helps control atmospheric levels of carbon dioxide. Human activities are altering the flows of energy and the cycling of key nutrients through ecosystems.
