Question

dioxide concentrations contribute to global warming. consequently, human actions pose challenges to the stability of the carbon cycle and have broad environmental consequences. what process naturally moves carbon through ecosystems and helps maintain equilibrium in the carbon cycle? deforestation photosynthesis mining

Explanation:

Photosynthesis is a natural process where plants absorb carbon dioxide (a form of carbon) from the atmosphere and convert it into organic compounds (like glucose) using sunlight. This helps in moving carbon through ecosystems. Deforestation (cutting down trees) disrupts the carbon cycle as trees that would absorb carbon are removed. Mining is a human - induced activity (not a natural process for carbon movement in the context of the carbon cycle equilibrium as asked in the question) that can release carbon (e.g., from coal mining, which is a fossil fuel containing carbon). So, photosynthesis is the natural process that moves carbon through ecosystems and helps maintain equilibrium in the carbon cycle.

Answer:

B. photosynthesis
