b. Nitrogen cycle.
c. Oxygen cycle.​

Answer 1

Explanation:

The circulation of nitrogen between organisms and the atmosphere is called the nitrogen cycle.

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.

The oxygen cycle is the biogeochemical transitions of oxygen atoms between different oxidation states in ions, oxides, and molecules through redox reactions within and between the spheres/reservoirs of the planet Earth.
