GENERAL KNOWLEDGE

Detailed explanation-1: -Carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere and the atmosphere of the Earth through a biogeochemical cycle called Carbon Cycle.

Detailed explanation-2: -Phosphorous Cycle In this biogeochemical cycle, phosphorus moves through the hydrosphere, lithosphere and biosphere. Phosphorus is extracted by the weathering of rocks. Due to rains and erosion phosphorus is washed away in the soil and water bodies.

Detailed explanation-3: -Carbon cycles through the atmosphere, biosphere, geosphere, and hydrosphere via processes that include photosynthesis, fire, the burning of fossil fuels, weathering, and volcanism.

Detailed explanation-4: -The same atoms are recycled over and over in different parts of the Earth. 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.
