The correct answer is: C.Plants.

Explanation:

In terrestrial ecosystems, plants are the primary organisms responsible for removing the most carbon from the atmosphere through the process of photosynthesis. During photosynthesis, plants absorb carbon dioxide (CO₂) from the atmosphere and use sunlight to convert it into glucose (C₆H₁₂O₆) and other organic compounds. This process not only provides the carbon needed for plant growth but also removes significant amounts of CO₂ from the atmosphere, helping to regulate the Earth's carbon levels.

Here's why the other options are less impactful:

A.Bacteria: Some soil bacteria can fix CO₂, but their contribution is minor compared to that of plants. Most of them function as decomposers, releasing carb...
