Answer:
The correct answer is- Heterotrops
Step-by-step explanation:
Heterotrophs are organisms that are not able to produce their food and depend on others to obtain a source of organic carbon or nutrition. Heterotrophs are consumers and can be primary, secondary, tertiary consumers but they are not producers and are dependent for their survival on producers directly or indirectly.
All animals living on the earth are heterotrophs and most of the fungi and bacteria are also heterotrophs. Heterotrophs can be herbivores, omnivores or carnivores.
Therefore the organisms that gain carbon and energy from other organisms are called heterotrophs.
