Please help Most ovens we use at home are powered by electricity or natural gas. These ovens use fossil fuels. Describe why the energy used by a solar oven is considered a clean source of energy.

Explanation:

Clean energy are renewable energy. This are energy from natural sources that are renewed without extra cost. Sun, wind, water are examples of renewable natural resources that helps generate clean energy.

The energy are refer to as clean because, they do not lead to any deposit of gasses that can affect the environment leading to environmental pollution. They have little or no side effects, no combustions or release of gases that are toxic or can deplete the environment as in the case of non- renewable energy.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
