Correct answer: C) Nutrients are circulated throughout the biosphere
Biogeochemical cycles are cycles by which essential elements of a living organism are circulated continuously. It consider the biological, chemical, and geological aspect of each cycle.
The most important biogeochemical cycles are nitrogen cycle, carbon cycle, water cycle, oxygen cycle and phosphorous cycle.
Biogeochemical cycle always have a state of equilibrium, and the state of equilibrium is attained when there is balance in cycling of element among the compartment.
Explanation:
Catalase test demonstrate the presence of an enzyme called catalase, that catalyses the release of oxygen from hydrogen peroxide. It is used to tell the difference between the non-catalase producing bacteria from those bacteria that produces an enzyme catalase. Catalase is produced by the bacteria that respire using oxygen. If an organism produces catalase, bubbles of oxygen are produced when hydrogen peroxide is added to it.
