Leguminous plants like pea and soya bean have the nitrogen fixing bacteria Rhizobium in their root nodules. The nitrogen fixed by this bacteria are taken up by herbivores which eat the palnts and then to carnivores which eat herbivores.

∙ 13y agoMost of the leguminous plants have root nodules. Pea and gram also belong to that family. This nodulation is caused by symbiotic microorganisms like Azatobactor. These microbes enter the roots from the soil and form nodules.

Bacteria in root nodules change nitrogen gas into what form?
ammonia
Where do most Nitrogen Fixation bacteria live?
Legumes have nirtifying bacteria in their roots, but mostly they are found in the soil.
What type of plants have root nodules?
Root nodules are swollen structures present present in roots of leguminous plant which belong to family Fabaceae e.g. Pisum sativum , Medicago , Arachis . This family is the second largest family of Dicots and second most important family from economic point of view.These root nodules are formed by Bacteria named Rhizobium. These Bacteria are nitrogen fixing bacteria i.e. they trap N2 from air and convert it into NO3 which is used as fertilizer by plants. There is symbiotic relation between legume roots and N2 fixing Bacteria .They increase soil fertility .
What do root nodules help the plant obtain?
Root nodules contain nitrogen fixing bacteria which help a plant to obtain nitrogen compounds, which are needed for the production of protein (and although plants do not contain as much protein as animals do, they still need a certain amount of it).
What is the relationship between the plant and bacteria in root nodules?
The nodules contain bacteria which can convert atmospheric nitrogen into ammonia
Bacteria in root nodules change nitrogen gas into what form?

ewte
What is found in the root nodules of leguminous plants?
it is rhizobium
What is a plant swelling?
Plant parts are swollen in many cases due to storage of food. In some aquatic plants, some plant parts like leaf petiole are swollen due to air chambers so that these plants can float in water.
The knoblike root nodules of soybean plants are the sites of?
nitrogen fixation
Legumes enrich soil by adding nitrogen to it through their?
root nodules
Where are nitrogen fixing bacteria found on plants?
The root nodules. they fix the bacteria in the soil so it's the most sensible place!
