Answer 2

Answer:

this works like this

• a farmer grows a crop, say wheat
• wheat uses the soils nitrogen for its growth
• after growing wheat the farmer wants to plant rice
• but rice needs lot of nitro for growths which is already used by wheat
• so before planting rice the farmer plant beans
• the beans plant has the rizopus bacterium in its roots which replenish the nitrogen content
• plants like beans are called leguminous crops
