Which of the following does not show heterotrophic

Solution

There are two modes of nutrition in living beings. Autotrophic nutrition- Autotrophic nutrition means that simple inorganic substances are taken in and used to synthesise organic molecules. Energy is needed to achieve this. Plants are examples of autotrophic nutrition since they make food with the help of sunlight, nitrogen, water and other nutrients from the environment. Heterotrophic nutrition- Heterotrophic nutrition is the mode of nutrition in which organisms depend upon other organisms to survive. All animals and non green plants are heterotrophic. Heterotrophic organisms have to acquire and take in all the organic substances they need to survive. Except green plants, all other options are heterotrophic. Hence, option D is correct.
