Quizplus · Accepted Answer

The atmosphere contains approximately 78% nitrogen gas, making it the largest storage pool for nitrogen in ecosystems. While the ocean also contains a significant amount of nitrogen, it is primarily in the form of dissolved nitrate and ammonia, rather than atmospheric nitrogen gas. Vegetation and legumes also play important roles in nitrogen cycling, but they are not the largest storage pools.
