Question

State whether the following statement is true or false.

Rhizobium is a free-living nitrogen-fixing bacterium.

Answer 1

This statement is false.

Explanation:

Rhizobium is not a free-living nitrogen-fixing bacterium.
It is a symbiotic nitrogen-fixing bacterium that lives inside the root nodules of leguminous plants (such as peas, beans, and lentils). It fixes atmospheric nitrogen into ammonia only when inside the host plant.
