N2 fixation.<\/p>\n<p>Nitrogen fixation is the process by which atmospheric nitrogen (N2) is converted into ammonia (NH3). This process is essential for life on Earth, as ammonia is a key nutrient for plants. Nitrogen fixation is carried out by a variety of organisms, including bacteria, archaea, and lightning.<\/p>\n<p>Industrial pollution can contribute to the release of nitrogen into the atmosphere, but this is not a natural process. The nitrogen cycle is the natural process by which nitrogen is recycled between the atmosphere, soil, and living organisms. Absorption of N2 is the process by which plants take up nitrogen from the soil.<\/p>\n<p>In conclusion, the correct answer is A.
