Question

what are the three ways that nitrogen can become \fixed\ by either natural or human - made processes?
through bacterial action, lightning strikes, or industrial processes for making fertilizer
through evaporation, condensation, and transpiration
through erosion, drought, and wave action

Explanation:

The correct option describes the natural (bacterial action, lightning) and human-made (industrial fertilizer production) processes that convert atmospheric nitrogen into a usable, fixed form. The other options reference water cycle processes and geological/weather events unrelated to nitrogen fixation.

Answer:

through bacterial action, lightning strikes, or industrial processes for making fertilizer
