Carbon cycle represents the movement of carbon in elemental and combined states on earth.

Carbon cycle represents the movement of carbon in elemental and combined states on earth. Diamond and graphite are the elemental forms of carbon and in a combined state, it is found as carbonates in minerals and as carbon dioxide gas in the atmosphere. Carbon Cycle Definition Carbon cycle can be defined as the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth. Carbon Cycle Steps Following are the main steps that are involved in the process of the carbon cycle:

Carbon Cycle Diagram The carbon cycle diagram below explains well the flow of carbon along different paths – [Image will be Uploaded Soon] Carbon Cycle on Land Carbon in the atmosphere is present in the form of carbon dioxide. Carbon enters the atmosphere through natural processes like respiration and industrial applications like burning fossil fuels. The process of photosynthesis involves the absorption of CO 2 by plants to produce carbohydrates. The equation is as follows: CO 2 + H 2 O + energy → CH 2 O +O 2 Carbon compounds are passed along the food chain from the producers to consumers. The majority of the carbon exists in the body in the form of carbon dioxide through respiration. The role of decomposers is to eat the dead organism and return the carbon from their body back into the atmosphere. The equation for this process is: CH 2 O +O 2  → CO 2 + H 2 O Oceanic Carbon Cycle This is essentially a carbon cycle but within the sea. Ecologically, oceans absorb more carbon than it gives out. Hence, it’s called a “carbon sink.” Marine animals convert carbon to carbonate and this forms the raw building materials required to make hard shells, almost like the ones found in clams and oysters. When organisms with carbonate shells die, their body decomposes, leaving their hard shells. These accumulate on the seafloor and are eventually broken down by the waves and compacted under enormous pressure, forming limestone. When these limestone rocks are exposed to air, they get weathered and the carbon is released back into the atmosphere as carbon dioxide. Importance of Carbon Cycle Even though CO 2 is found in small traces within the atmosphere, it plays an important role in balancing the energy and traps the long-wave radiations from the sun. Therefore, it acts like a blanket over the planet. If the carbon cycle is disturbed it’ll end in serious consequences like climatic changes and heating . Carbon is an integral component of every life form on earth. From proteins and lipids to even our DNA. Furthermore, all known life on earth is predicated on carbon. Hence, the carbon cycle, alongside the organic process and oxygen cycle, plays an important role within the existence of life on earth. Key Points on Carbon Cycle

Q1. What is a Carbon Cycle?  Ans – Carbon cycle can be defined as the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth. Q2. What are the Types of the Carbon Cycle? Carbon Cycle can be classified into two types based on the duration of the process into two types:

Q3. What is the Importance of Carbon Cycle?  Ans – Even though CO 2  is found in small traces within the atmosphere, it plays an important role in balancing the energy and traps the long-wave radiations from the sun. Therefore, it acts like a blanket over the planet. If the carbon cycle is disturbed it’ll end in serious consequences like climatic changes and heating . Carbon is an integral component of every life form on earth. From proteins and lipids to even our DNA. Furthermore, all known life on earth is predicated on carbon. Hence, the carbon cycle, alongside the organic process and oxygen cycle, plays an important role within the existence of life on earth. Q4. What are the Steps of Carbon Cycle? Ans – Following are the main steps that are involved in the process of the carbon cycle:
