Some species of nitrogen-fixing bacteria have adapted to grow in nodules of legumes such as peas and clover. these bacteria make nitrogen available to the plant and in turn, receive nutrients from the tissues of the plant. this type of interaction is known as

The correct answer is Mutualism.

Mutualism is type of interaction that describes two species, which are living in close proximity and each species is benefited by the action of other species.

Here, the nitrogen fixing bacteria provides nitrogen to the plants by fixing it in the root nodules. In turn, they are receiving nutrients from the plant tissue. This means that both the species are benefited in this way.

Thus, this type of interaction is mutualism.
