Show with the help of a sketch that the plants are ultimate source of food
Answers
Plants prepare their own food, from the energy that they obtain from the Sun, through the process of photosynthesis. Due to this reason, plants are also called autotrophs. All the other organisms depend on plants for their nutritional requirements and are called heterotrophs. Plants serve as food for all the heterotrophs directly or indirectly. Dead and decaying autotrophs and heterotrophs further serve as a source of nutrition for saprotrophs. Hence, it can be said that “plants are the ultimate source of food”.
