Yeah im here and i am alos getting bored to
what are you doing and how is your day ?
so this is right answer
For reasons that are unclear, no eukaryotic enzymes can break the triple bond of N2. The reduction of N2 to NH3 (nitrogen fixation) is limited to prokaryotes and is catalysed by nitrogenase. Since most of the nitrogen entering the biosphere (around 100 million metric tonnes of N2 per annum) does so through nitrogenase activity (lightning contributes about 10%), those plants that associate with nitrogen-fixing bacteria have a significant selective advantage under conditions of limiting nitrogen.
I don’t get it. What is the question asking?

This would be 'chemical' weathering.
Acid rain would react with the minerals in the rocks, causing them to break down.
