Which of the following crops contains Nitrogen fixing bacteria ?

Wheat
Paddy
Maize
Peas

The correct answer is (d) Peas.

Nitrogen fixing bacteria are bacteria that can convert atmospheric nitrogen into ammonia, which is a form of nitrogen that plants can use. This process is called nitrogen fixation.

Peas are a legume, which means that they have a symbiotic relationship with nitrogen fixing bacteria. The bacteria live in nodules on the roots of the peas, and they convert atmospheric nitrogen into ammonia, which the peas can use.

Wheat, paddy, and maize are not legumes, and they do not have a symbiotic relationship with nitrogen fixing bacteria. Therefore, they do not contain nitrogen fixing bacteria.

In addition to peas, other legumes that contain nitrogen fixing bacteria include beans, lentils, and soybeans.
