CARBON CYCLE – History, Meaning, Steps, Important, Flow Chart, Brief Explanation, Carbon cycle on land, Carbon cycle on ocean

The global carbon cycle is now commonly divided into the following major carbon reservoirs, which are linked by exchange pathways: The ambiance. The biosphere of the land. The ocean, which includes dissolved inorganic carbon as well as living and non-living marine biota.

Carbon exists in two forms in the Earth’s atmosphere: carbon dioxide and methane. Both of these gases absorb and retain heat in the atmosphere, contributing to the greenhouse effect. Formal paraphrase Methane has a greater greenhouse effect per volume than carbon dioxide, but it exists in much lower concentrations and has a shorter lifetime, making carbon dioxide the more important greenhouse gas of the two. Formalized paraphrase

Carbon dioxide is primarily removed from the atmosphere by photosynthesis and enters the terrestrial and oceanic biospheres. Carbon dioxide dissolves directly from the atmosphere into bodies of water (oceans, lakes, and so on), as well as in precipitation as raindrops fall through the atmosphere. When carbon dioxide is dissolved in water, it reacts with water molecules to form carbonic acid, which contributes to ocean acidification. It can then be absorbed by rocks as a result of weathering. It can also acidify other surfaces it comes into contact with or be washed into the ocean.

Who discovered the carbon cycle?

Joseph Priestley

Humphry Davy popularised the carbon cycle, which was discovered by Joseph Priestley and Antoine Lavoisier.

What are the importance of carbon cycle in nature?

The carbon cycle is important in ecosystems because it transports carbon, a life-sustaining element, from the atmosphere and oceans to organisms back again

If the balance between these two reservoirs is thrown off, serious consequences such as global warming and climate disruption may occur. Scientists are currently investigating ways for humans to generate energy from non-carbon-containing fuels. Nuclear power, solar power, wind power, and hydropower are all examples of renewable energy source.

Carbon cycle brief explanation?

The carbon cycle is the process by which carbon moves from the atmosphere to the Earth and its organisms and back. Carbon movement from the atmosphere to the oceans: The oceans and other bodies of water absorb about a quarter of the carbon dioxide and convert it to carbonates.

The carbon cycle is comprised of the following processes:

a. Photosynthesis: This process involves plants absorbing atmospheric carbon in the form of carbon dioxide gas and emitting oxygen gas.

b. Respiration: Plants and animals respire, which results in the breakdown of glucose stored in the plants and animals, releasing CO2, water, and energy.

c. Decomposition: Dead plants and animals are decomposed in this process, releasing carbon into the environment.

d. Combustion: The combustion of fossil fuels emits carbon dioxide gas into the atmosphere as a by product.

As a result, the amount of carbon dioxide produced is nearly equal to the amount of carbon dioxide consumed, and thus its concentration in air remains same.

What are the steps of the carbon cycle?

*Carbon is transferred from the atmosphere to plants.

*It is transferred from plants to animals.

*Carbon is transferred from plants and animals to soils.

*Carbon is transferred from living things to the atmosphere.

*When fossil fuels are burned, carbon is released into the atmosphere. *Carbon is transferred from the atmosphere to the oceans

What are the different types of carbon cycles?

*Short term – This type occurs over a short period of time. It is so named because carbon flows across the various carbon reservoirs in a matter of days, months, or years.

*Long term – This type occurs over thousands of years. Before being released, the excess carbon from the short-term cycle is stored for a long time.

What is carbon cycle? Explain in short.

Carbon Cycle is a biogeochemical cycle where various carbon compounds are interchanged among the various layers of the earth, namely, the biosphere, geosphere, pedosphere, hydrosphere and atmosphere.

Describe the Carbon Cycle on Land

Carbon dioxide is the most common form of carbon in the atmosphere. Carbon enters the atmosphere through natural processes such as respiration as well as industrial processes such as the combustion of fossil fuels. Photosynthesis is the process by which plants absorb CO2 to produce carbohydrates. The formula is as follows:

(CH2O)n +O2 + CO2 + H2O + energy

Carbon compounds are transferred from producers to consumers via the food chain. The majority of carbon in the body exists in the form of carbon dioxide as result of respiration. Decomposers eat dead organisms and recycle the carbon in their bodies back into the atmosphere.

Explain The Oceanic Carbon Cycle

This is essentially a carbon cycle, but it takes place in the sea. Oceans, from an ecological standpoint, take in more carbon than they emit. As a result, it is referred to as a “carbon sink.” Marine animals convert carbon to calcium carbonate, which provides the raw materials needed to build hard shells similar to those found in clams and oysters.

When organisms with calcium carbonate shells die, their bodies decompose and their hard shells are left behind. These build up on the seafloor and are eventually broken down by the waves and compacted under enormous pressure, resulting in limestone.

When these limestone rocks are exposed to air, they weather and the carbon is released back into the environment as carbon-di-oxide.
