What is the best definition for biogeochemical cycles?
a. pathways by which carbon and water are transferred between organisms and the environment
b. pathways by which matter is transferred between organisms and the environment
c. pathways by which phosphorus and nitrogen are transferred between living organisms and the environment
d. pathways by which waste is transferred between organisms and the environment

B. Pathways by which matter is transferred between organisms and the environment

Explanation:

Biogeochemical cycles can be define as cycles which involves the natural pathways by which inorganic and organic matter is transferred within the living organisms and the environment.

The essential elements such as water, carbon, phosphorous, nitrogen and oxygen are transferred among the various spheres of the earth like atmosphere, biosphere, lithosphere and others which forms the integral part of the non-physical environment.
