The Nitrogen Cycle The Nitrogen Cycle The nitrogen cycle is a complex biological cycle involving the recycling of usable nitrogen.
Check new design of our homepage! Let us trace the path of carbon as it constantly moves through various steps of the carbon cycle. BiologyWise Staff Last Updated: May 21, Carbon is the fourth most abundant chemical element in the universe and forms the building blocks of the living world along with hydrogen and oxygen.
In fact, its concentration in the biotic world living world is almost times more than that in the abiotic non-living world. Other than this, carbon is an important element that forms a blanket around the Earth. It traps the heat of the sun within the atmosphere and hence prevents the Earth from freezing.
There is a constant exchange of carbon between the biotic and the abiotic world, thus forming a cycle which is called the carbon cycle.
This cycle plays an important role in maintaining proper levels of carbon in the Earth's atmosphere. Steps of the Carbon Cycle Carbon is regularly being exchanged among the atmosphere, land, water, and the living beings.
In fact, it is constantly on the move! Let us understand how the carbon cycle works. CO2 Used by Plants for Photosynthesis - The primary producers green plantsalso known as photoautotrophs, are constantly removing carbon dioxide from the atmosphere through the process of photosynthesis the process in which green plants make food for themselves in presence of sunlight.
Certain bacteria, also referred to as chemoautotrophs, use carbon dioxide to synthesize the organic compounds they need. Consumption by Animals - The carbon present in the food made by green plants reaches animals through the food chain.
Carnivorous animals receive this carbon when they eat other animals. Ocean Intake - Carbon dioxide is continuously being dissolved in the seas and oceans through the process of diffusion. Once dissolved, this carbon dioxide may remain as it is in the marine waters or may get converted into carbonates CO and bicarbonates HCO The carbon dioxide dissolved in water is used by marine plants for photosynthesis.
The carbonates are converted into calcium carbonate by certain marine organisms. This calcium carbonate is used by corals and oysters to make their shells. When these organisms die, their shells deposit on the sea floor and finally turn into sedimentary rocks.
Decay and Decompose - When living organisms die, their bodies decay and decompose. This happens due to various natural reasons. The energy as well as the carbon dioxide present in their bodies is released by the chemical reactions taking place on the body.Starch is formed after the Calvin Cycle in the Stroma.
Carbon dioxide is present in the air and the water is gained from precipitation or morning dew. The water is broken down in photosystem I (sourcing invisible light of nm) by photolysis.

The exception to this is when humans extract it in the form of oil, coal, and natural gas, and release it back into the atmosphere by burning it. Cellular respiration and photosynthesis are critical in the continued cycle of energy to sustain life as we define it.

Cycles in biology A cycle is a series of events repeated in the same order. Cycles are a major aspect of biology which occurs in a ecosystem, plants and animals. One cycle which is part of the ecosystem is the water cycle. The sun heats water in oceans and seas and water evaporates as water vapour into the air/5(1).
