Explanation: 1.5 Marks
Nitrogen fixation is a process by which free atmospheric nitrogen is converted into nitrogen compounds. In nature, nitrogen is fixed during lightning or by nitrogen-fixing bacteria and blue-green algae.
Leguminous plants like pea and soya bean have the nitrogen - fixing bacteria called Rhizobium right at their root nodules. The nitrogen fixed by these bacteria are then taken up by the plants and stored in their tissues as plant proteins. This stored nitrogen then passes from these plants to herbivores and then to carnivores.
