Bacteria in the soil converts this nutrient into a usable form. Plants take up the usable nutrient through the soil and assimilate it into proteins, making it part of the plant. An animal eats the plants, and the nutrient becomes part of the animal. When the animal dies, it decomposes, returning the nutrient back to the soil. Which cycle is being described?

Fossil fuels are normally stored in a reservoir deep in the Earth. The carbon in fossil fuels, including coal and oil, are essentially locked out of the natural carbon cycle due to their location deep in the Earth. Humans have found a way to access and utilize this carbon. Identify a risk for accessing this carbon.
