What is nitrogen cycle and carbon cycle?
Carbon Cycle: The fixed carbon is released to the atmosphere by respiration, combustion, and protoplasmic decay. Nitrogen Cycle: The fixed nitrogen is released to the atmosphere by decay and denitrification.
What are the 3 main nutrient cycles in an ecosystem?
Elements in the Biosphere The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle. These three cycles working in balance are responsible for carrying away waste materials and replenishing the ecosystem with the nutrients necessary to sustain life.
What are the steps of the nutrient cycle?
In the process, nutrients get absorbed, transferred, released and reabsorbed. It is a natural recycling system of mineral nutrients. Nutrients consumed by plants and animals are returned to the environment after death and decomposition and the cycle continues.
What are the steps of the carbon cycle?
The carbon cycle is divided into the following steps:
- Entry of Carbon into the Atmosphere.
- Carbon Dioxide Absorption By Producers.
- Passing of the Carbon Compounds in the Food Chain.
- Return of the Carbon To the Atmosphere.
- Short Term.
- Long Term.
- Essential For Life.
- Important For the Maintenance of the Balance in Ecosystems.
What is nitrogen cycle process?
Nitrogen Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, decay and putrefaction.
What do you mean by nitrogen cycle?
The nitrogen cycle is a repeating cycle of processes during which nitrogen moves through both living and non-living things: the atmosphere, soil, water, plants, animals and bacteria. In order to move through the different parts of the cycle, nitrogen must change forms.
What are the 4 stages of the nitrogen cycle?
Four processes participate in the cycling of nitrogen through the biosphere: (1) nitrogen fixation, (2) decay, (3) nitrification, and (4) denitrification.
What role does nitrogen play in a nutrient cycle?
– Summary. The nutrient cycle is a system where energy and matter are transferred between living organisms and non-living parts of the environment. – References. Andrews, S. (2011, September 19).

What are the 5 stages of the nitrogen cycle?
Five stages of the nitrogen cycle include fixation, uptake, mineralization, nitrification, and dentrification. All five stages are carried out by microorganism whereas the fixation of carbon is done mainly by plants. Humans need to interfere in the nitrogen cycle by adding nitrogen in a form that’s useful to plants.
What is nitrogen cycle and why is it important?
Food industry. Nitrogen gas is also used to provide an unreactive atmosphere.…
