Detailed explanation-1: -All the non-green plants and animals, inclusive of human beings, are called heterotrophs. The non-green plants lack chlorophyll which is necessary to carry out the process of food referred to as photosynthesis. Therefore, they depend on other organisms i.e. plants and animals in order to obtain food.
Detailed explanation-2: -Non-green plants such as fungi and bacteria feed on dead and decaying matter to obtain their nourishment.
Detailed explanation-3: -Non-green plants do not have chlorophyll (green pigment) necessary to carry out the process of synthesizing food (photosynthesis). Hence, they have the heterotrophic mode of nutrition. Example: Indian pipe plants obtain food from roots of photosynthetic trees.
Detailed explanation-4: -“Heterotroph is an organism that is unable to synthesize its own food, and therefore, has to rely on other sources, specifically plant and animal matter.” All animals and non-photosynthetic plants are classified as heterotrophs since they are unable to prepare food.
