explain the role of organisms in the carbon cycle and oxygen cycle
Answers
Answer:
Plants absorb carbon from the environment in photosynthesis and return it in respiration. Animals obtain their carbon by eating plants; they release carbon in respiration. Micrororganisms (such as fungi and bacteria) return carbon to the environment when they decompose dead plants and animals.
Explain the role of organisms in the carbon cycle and oxygen cycle?
:
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
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.
