Legumes, a type of plant, require Rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen during photosynthesis. Rhizobia use the legumes for food. What would most likely happen to the legume population if Rhizobia suddenly became extinct? become extinct learn to fix nitrogen benefit in the long run stay the same

Become extinct

Explanation: The legumes and the Rhizobia use each as support, they are in a mutualism relationship, so if Rhizobia becomes extinct, it will affect legumes because they will not be able to get the needed nitrogen during photosynthesis. This will result in them not making food, which will eventually lead to all of the plants dying off, becoming extinct.

Become extinct

GOOD LUCK
