Which of th following cycles is crucial to living organisms
All of the above
The living component of the ecosystem consists of both living and non living components. The living components of the ecosystem consists of plants and animals.
The non-living components of ecosystem consists rocks, river, soil et cetera. The living components of the ecosystem needs to depend on the non living and living components.
The phosphorous, nitrogen and carbon cycle are important for the living components of the ecosystem.
d.ALLOF THE ABOVE
The correct answer is d. all of the above.
The cycling of essential elements of living organism throughout the ecosystem is referred to as biogeochemical cycles. For example, carbon cycle, water cycle, phosphorus cycle, nitrogen cycle, etc.
All these cycles are essential for the survival of the living organisms. They play important role in life processes (such as metabolism, action potential etc) as well as form the basis of structure.
For example carbon, nitrogen, hydrogen, phosphorus, water are the basic elements used in the formation of DNA, RNA, amino acids etc.
The reproductive cycle is crucial.
Water is needed for by everything, Plants need carbon dioxide to make make their food in process called photosynthesis, (plants then excrete oxygen which mammals need) and I believe phosphorus are used by plants for growth and survival.
