Interaction between two species in which both are benefited
(i) Rhizobium in the roots (nodules) of legumes
(ii) Mycorrhiza / Glomus with the roots of higher plants.
Detailed Answer :
Mutualism: It is relationship between two organism in which both are benefited from each other and no one is harmed.
Examples are as follows :
Commercial exploitation of mycorrhiza in agriculture. Mycorrhiza is an association of the soil fungus with the roots of higher plants. Farmers use mycorrhiza commercially in agriculture as it improves the soil quality and reduces soil erosion by improving plant rooting capacity. The fungal hyphae spread into the root tissues and help the plants to optimally use the soil's water and minerals. Thus, to increase the yield of plants and to replenish the soil nutrients, these are commercially exploited in agriculture.
