Question

A farmer has a nitrogen-depleted field. To address this shortage, she plants beans to take advantage of the ability of leguminous plants to carry out:

a) Nitrogen fixation
b) Denitrification
c) Nitrification
d) Ammonification

Answer 1

The correct answer is Nitrogen fixation. Leguminous plants, such as beans, have a symbiotic relationship with nitrogen-fixing bacteria known as rhizobia. These bacteria convert atmospheric nitrogen gas (N2) into a usable form, such as ammonia (NH3), which is then used by the plant for nucleotide and protein formation.

Step-by-step explanation:

The correct answer is a) Nitrogen fixation. Leguminous plants, such as beans, have a symbiotic relationship with nitrogen-fixing bacteria known as rhizobia. These bacteria live in root nodules of legumes and convert atmospheric nitrogen gas (N₂) into a usable form, such as ammonia (NH₃), which is then used by the plant for nucleotide and protein formation. This process helps replenish the nitrogen in the soil, addressing the shortage in a nitrogen-depleted field.
