Question

Define biogeochemical cycle and describe carbon cycle??

Answer 1

A biogeochemical cycle is one of several natural cycles, in which conserved matter moves through the biotic and abiotic parts of an ecosystem. ... The abiotic components can be subdivided into three categories: thehydrosphere (water), the atmosphere (air) and the lithosphere(rock).



The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbondioxide from the air and use it to make food. Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration.
