Explain Carbon Cycle and Phosphorus Cycle
Answers
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to make Earth capable of sustaining life. It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks.
Answer:
CARBON CYCLE:
Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.
Following are the major steps involved in the process of the carbon cycle:
Carbon present in the atmosphere is absorbed by plants for photosynthesis.
These plants are then consumed by animals, and carbon gets bioaccumulated into their bodies.
These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.
Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.
These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.
PHOSPHORUS CYCLE:
Phosphorus cycle is a biogeochemical process that involves the movement of phosphorus through the lithosphere, hydrosphere and biosphere.
Following are the important steps of phosphorus cycle:
Weathering
Absorption by Plants
Absorption by Animals
Return to the Environment through Decomposition
