Question

The carbon cycle is a complex series of processes through which all of the carbon atoms on Earth move through the planet's organisms, atmosphere, ocean, and solid rock.


As demonstrated by the carbon cycle, matter on Earth is generally
A.
released into space once it reaches the atmosphere.
B.
created and destroyed by the basic life processes of organisms.
C.
recycled continually through the spheres of the Earth.
D.
absorbed into the Earth's core where it can no longer be used.

Answer 1

C. Recycled continually through the spheres of the Earth.

Explanation: The carbon cycle shows carbon moving among the atmosphere, biosphere, hydrosphere, and lithosphere via processes like photosynthesis, respiration, decomposition, and sedimentation — matter is conserved and recycled, not destroyed or lost to space.
