Detailed explanation-1: -Most of the energy needed to cycle matter through earth’s systems comes from the sun. The cycling of matter. Because there are only finite amounts of nutrients available on the earth, they must be recycled in order to ensure the continued existence of living organisms.
Detailed explanation-2: -Natural cycles of matter are important for life and the environment. They allow the transport and long-term storage of matter. They also make essential elements, like carbon and nitrogen, available to living things for biosynthesis.
Detailed explanation-3: -The rest of this concept takes a closer look at four particular biogeochemical cycles: the water, carbon, nitrogen, and phosphorus cycles.
Detailed explanation-4: -Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy.
Detailed explanation-5: -Dead producers and consumers and their waste products provide matter and energy to decomposers. Decomposers transform matter back into inorganic forms that can be recycled within the ecosystem.
