​

Answer 1

Answer:

2. Rhizobium and leguminous plants live in a symbiotic association with each other. In this, both the organisms are benefited from each other. The bacteria fix atmospheric nitrogen and make it available to the plants. On the other hand, Rhizobium receives nutrition from the plant in the form of organic acids.

4. Heterotrophic nutrition is of three types – saprophytic, parasitic and holozoic. Saprophytic or Saprotrophic Nutrition: It is a mode of heterotrophic nutrition in which food is obtained from organic remains like dead organisms, excreta, fallen leaves, broken twigs, food articles, etc.
