Question

evaporation and nitrogen fixation

decomposition and energy transfer

there's no such thing as the carbon cycle

photosynthesis and cellular respiration

Answer 1

the answer is the last one

Step-by-step explanation:

here is the definition:

(i know how to explain the answer, its merely unnecessary being that there is an offical definition.)

the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

Answer 2

Carbon-cycle is the cyclic process in which Carbon is between different spheres of the Earth. Carbon is a major component of all the organic compounds as well as many minerals.

Carbon is inter converted through the main processes: photosynthesis and respiration. Carbon dioxide incorporates in the living tissues through photosynthesis and is returned to the environment through the process of respiration, death and decay of living organisms etc.
