Question

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

Explanation:

Photosynthesis is a natural process where plants take in carbon dioxide ($CO_2$) and convert it into organic compounds (like glucose) using sunlight. This helps move carbon from the atmosphere into the biosphere. Deforestation (cutting down trees) reduces the number of plants that can perform photosynthesis, disrupting the carbon cycle. Mining is the extraction of minerals and doesn't directly move carbon in a way that maintains equilibrium in the carbon cycle. Pollution (e.g., releasing excess $CO_2$ from burning fossil fuels) also disrupts the carbon cycle. So, among the options, photosynthesis is the natural process that moves carbon through ecosystems and helps maintain carbon - cycle equilibrium.

Answer:

photosynthesis
