Answer:
(a) The process of intake and utilisation of nutrients like carbohydrates, proteins, vitamins and fats by an organism is known as nutrition. Nutrition is necessary for an organism because it provides it with the appropriate amount of nutrients that are needed for the maintenance of life and survival.
(b) Following are the different modes of nutrition:
(i) Autotrophic nutrition:
It is the mode of nutrition in which an organism makes its own food by the process of photosynthesis. Green plants are autotrophs.
(ii) Heterotrophic nutrition:
It is the mode of nutrition in which an organism obtains its food from the autotrophs or other heterotrophs. All animals are heterotrophs.
(c) The mode of nutrition in a (i) roundworm and a (ii) Plasmodium is parasitic.
