Question

what process naturally moves carbon through ecosystems and helps maintain equilibrium in the carbon cycle? pollution photosynthesis deforestation mining

Explanation:

To solve this, we analyze each option:

• Pollution: Human - caused, disrupts cycles, not a natural balancing process.
• Photosynthesis: Plants take in $CO_2$ (carbon) and release $O_2$, a key natural process in the carbon cycle that helps maintain equilibrium.
• Deforestation: Human - induced, reduces carbon absorption, disrupts the cycle.
• Mining: Human - made, extracts resources, not related to natural carbon cycle balance.

Answer:

B. photosynthesis
