Question

what is carbon cycle​

Answer 1

hey mate!!!!

♠️ Here's your answer

↪️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.

➡️The carbon cycle was discovered by Joseph Priestley and Antoine Lavoisier, and popularized by Humphry Davy.

$\huge\underline\mathfrak\color{blue}Answer$

Carbon is present in the compound form in atmosphere ie., CO2, carbonates in water which forms limestone.

CO2 is taken by plants during photosynthesis to form organic compounds like glucose, carbohydrates, these plants are further eaten by animals, and decomposition gives CO2 back to the atmosphere. Plants and animals which get buried under the earth and does not decompose form coal and petroleum respectively.

Animals and plants also release CO2 back to the atmosphere during respiration.
