Question

Are leguminous plants rich in nitrogen fixation?

Answer 1

Nitrogen fixation

1. The process of converting atmospheric nitrogen into usable form is called nitrogen fixation.
2. It occurs naturally through lightning or by a biological process with the help of nitrogen-fixing microbes.
3. Not all plants can use atmospheric nitrogen directly. They have to be converted into usable nitrites and nitrates.

Legumes

1. Legumes belong to the family Fabaceae.
2. The seeds of legume plants are consumed as pulses.
3. Examples include beans, lentils, and peas.
4. Legumes are efficient in nitrogen fixation due to having a symbiotic relationship with nitrogen-fixing microbes.
5. Microbes such as Rhizopus live inside specialized roots of the legumes called nodules and convert atmospheric nitrogen into absorbable ammonia form.
6. In return, the microbes derive nutrition and a safe habitat for their survival.
7. This symbiotic relationship allows legumes to grow in nitrogen-deficient soil.
