What term describes the natural process by which certain bacteria convert atmospheric nitrogen gas into compounds that plants can absorb and use?

Explanation

Nitrogen fixation is the natural process by which certain bacteria, some living freely in soil and others in a symbiotic relationship within the root nodules of legume plants, convert unreactive nitrogen gas from the atmosphere into nitrogen-containing compounds that plants can absorb and use to build proteins and other essential molecules. This process is essential because although nitrogen gas makes up the majority of Earth’s atmosphere, most plants and animals cannot use it directly in that gaseous form. Farmers sometimes rotate in nitrogen-fixing crops like beans or peas to naturally help replenish soil nitrogen levels. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
