Question 23 • Biology

What would most likely happen to life on Earth if the carbon cycle stopped?

Answer
A
Life would cease to exist.
B
Only animals would be affected.
C
Life would continue unchanged.
D
Only plants would be affected.

Explanation

Carbon is a basic building block of living things and is continually recycled through organisms and the environment. If the carbon cycle stopped, organisms would no longer receive or recycle carbon in the ways needed to sustain life, disrupting food webs and essential processes. Therefore, life would cease to exist, rather than only plants or animals being affected.
