Carbon and Nitrogen cycle are the two important cycle that organisms need..
Explanation:
Carbon cycle is a process where carbon from the atmosphere travels to the organisms , carbon dioxide from the atmosphere is used by plants for the process of photosynthesis.
Through the process of photosynthesis it enters in the plant body and then it enters to the body of the heterotrophs. Again through the process of respiration and decomposition it goes to the atmosphere. This is referred to as the short term process . Some also enters in long- run process such as fossil fuels.
Nitrogen is a crucial part of many cells such as protein, amino acid as well as DNA.
The process of converting nitrogen into various chemicals and then it gets circulated in the atmosphere , terrestrial as well as marine ecosystem. The process is carried by both physical as well as biological process such as nitrification, fixation.
