Why is a carbon dioxide cycle called a cycle?

Answer 1

it is called cycle because when we exhale we gives off carbon dioxide, and it is absorb by plants, then after the process called photosynthesis it gives off oxygen to the atmosphere, then now we inhale it and after we inhale we exhale the carbon dioxide and goes to the atmosphere then absorb by plants, gives off oxygen, goes to the atmosphere, then inhale it and so on and so forth . . . . . . . . . . . . . . .

for shorth will go back and go back. not like the one way flow of energy that will remain.... . . . . . . . . . . . . . . . . . . . . . . .

Answer 2

The carbon cycle is the cycle in which carbon moves around...well, here's a "simple" description:

Humans take in oxygen and change it to carbon dioxide. Burning things and the fire itself, also releases carbon dioxide. It's not just humans; it's also animals like dogs and cats that take in oxygen and give off carbon dioxide. We do it with every breath. So, how come we don't run out of oxygen and have carbon dioxide in its place? Well, plants take in carbon dioxide and give off oxygen.

Go basically:

Animals breathe out carbon dioxide, burning things give off carbon dioxide, and plants take in carbon dioxide and give off the oxygen that we use and change to carbon dioxide.

It is a cycle because it keeps happening and happening and the carbon dioxide "goes around in a circle."

Answer 3

The carbon and Oxygen constantly moves in a circle of being converted to glucose in photosynthesis and then being broken down in respiration.

Answer 4

beacase it is a cycle
