Which best describes the carbon cycle? carbon retains the same form throughout
the movement of carbon through the biosphere
the measurement of carbon in water
carbon is converted to carbon dioxide in photosynthesis

the movement of carbon through the biosphere

Explanation:

Carbon cycle is one of the major biogeochemical cycles that occurs on Earth. It is the process whereby carbon moves or circulates throughout the earth. Carbon, which is a major component of many biological substances moves to and fro living organisms and the atmosphere in different forms.

Carbon is released and absorbed in different forms in the atmosphere. For example, carbon in form of carbondioxide (CO2) is released into the atmosphere by living organisms via the process of CELLULAR RESPIRATION. The CO2 is then absorbed by green plants for the process of PHOTOSYNTHESIS. The carbon is released back into the earth when decomposers degrade dead organisms. This process of recycling carbon via natural processes is called CARBON CYCLE.

Hence, the movement of carbon through the biosphere is the best description of carbon cycle in this question.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
