Question

Comment in detail on the carbon cycle.

Answer 1

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 2

The description of Carbon Cycle is :

In an individual, carbon is present in about 49% of the individual's dry weight. And 71% carbon is observed in the oceans in dissolved forms.

The cycle of carbon happens through 3 major regions or sites. These are - atmosphere, oceans and both living as well as dead individuals.

In atmosphere, carbon is given back in CO2 form which is released by plants and animals.

Also, wood burning, burning fossil fuels, forest fire that occurs, results in the release of carbon to the atmosphere.
