Answer 2

Answer:

hey mate here is your answer

Explanation:

Earth's atmosphere contains a huge pool of nitrogen gas (N2). But this nitrogen is “unavailable” to plants, because the gaseous form cannot beused directly by plants without undergoing a transformation. To beused by plants, the N2 must be transformed through a process called nitrogen fixation.
