Detailed explanation-1: -This type of cycle of atoms between living and non-living things is known as a biogeochemical cycle. All of the atoms that are building blocks of living things are a part of biogeochemical cycles. The most common of these are the carbon and nitrogen cycles.

Detailed explanation-2: -Like in the carbon cycle, plants are eaten by other consumers in the ecosystem, thus passing nitrogen through the food web. Nitrogen does not remain in living organisms forever. When organisms die the nitrogen is released back into the atmosphere and the soil, where it can be recycled into the nitrogen cycle again.

Detailed explanation-3: -Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.

Detailed explanation-4: -Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. Organisms obtain gases, water, and minerals from the environment and release waste matter (gas, liquid, or solid) back into the environment.

Detailed explanation-5: -The carbon cycle is nature’s way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
