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?

legumes depend on these bacteria for survival so if rhizobia go extinct the legume population would greatly decrease and even go extinct if they don’t find another way of getting nitrogen from the soil(mutualism with other bacteria such as cyanobacteria)

Rhizobium helps to legumes plants in fixing nitrogen, it plays major role in nitrogen cycle , if rhizobia suddenly became extinct the growth of legumes plants will slow down, and as a result production from crops will be affected

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
