Farmers often cultivate leguminous plants like gram or soybean in rotation with cereal crops like wheat. How does this practice show interdependence between living organisms?
Cereal plants provide shelter to farm insects
Rhizobium bacteria in root nodules fix atmospheric nitrogen into the soil
Gram plants absorb extra water to prevent root rot in wheat
Weeds cannot grow near leguminous crops
Solution
Rhizobium bacteria in the root nodules of leguminous plants convert atmospheric nitrogen into nitrates, enriching the soil for subsequent crop growth.
