उत्तर
The major reservoir of carbon on earth is ocean.
Explanation:
Deep trenches in the ocean, and even ocean water in general, are high in dissolved carbon and organic matter, both of which act as carbon sources. Furthermore, the ocean is the largest carbon reservoir, driven by nutrient leaching and precipitation from land.
