Question

What is biogeochemical cycle???​

Answer 1

A biogeochemical cycle is a process where a type of element moves through nature. An element moves through nature by the break down and build up of molecules the element is a part of. To give an example, think about carbon. Carbon is present in gaseous CO2 in the atmosphere. Vegetation sequesters CO2 through photosynthesis. Plants turn CO2 into sugars to store energy absorbed by the sun. These sugars are then stored by the plant for later catabolic purposes. When the plant dies the sugars, or otherwise stored carbon, in its body are broken down by microbes which take the carbon an convert it into a molecule for storing microbial energy. As certain microbes break down the carbon-bearing molecules of the plant they respire CO2 in the process . This is why its called a cycle. Its called biogeochemical because what is happening during the cycle is a chemical process occurring at the interface between biology and geology.

Answer 2

The process in which nutrients like nitrogen, carbon, oxygen and water are changed from one form to another is called biogeochemical cycle.
