Answer 2

$\huge\green{\mathfrak{Answer:-}}$

Rhizobium is found in root nodules of

$\pink{\boxed{pulses}}$

Explanation:

Pulses are grown in alteration with nutrient demanding crops because they improve soil fertility. The roots of such plants called leguminous plants form a cooperative association with certain soil bacteria known as nitrogen fixing bacteria(eg Rhizobium)

The bacteria enter the root through the root hairs and grow and multiply in the root. They convert atmospheric nitrogen into ammonia(NH₃) which the plant uses to make proteins(this process is called nitrogen fixing). In return the bacteria gets sugars from the plant and a moist environment to live in. Such a mutually beneficial association between two organisms is called symbiosis.

Some examples of leguminous crops:Pulses, beans, peas, grams.
