Solution :
HETEROTROPHIC NUTRITION | AUTOTROPHIC NUTRITION |
These organisms cannot synthesize their own food. | These organisms can synthesize their own food. |
These organisms depend on autotrophs for food either directly or indirectly. | Food can be synthesized from simple inorganic raw materials like carbon dioxide,and water. |
They take food from autotrophs and they have enzymes in their digestive system that can digest the intake food. | They prepare their own food and that can be transported to the whole body. |
Green pigment, chlorophyll, is absent in heterotrophs.Also they don’t need any pigments for nutrition | Green pigment, chlorophyll, is present in autotrophs. |
Heterotrophs can prepare their food at any time. | Food is prepared during day time with the help of the sunlight. |
They don’t require any photosynthetic process for the preparation of their food. | Autotrophs synthesis food by the process of photosynthesis |
All the animals are heterotrophs. Heterotrophs can also be classified as herbivorous animals which eat only plants. Eg : deer Carnivorous animals that eat other animals. Eg : tiger Omnivorous animals that can eat both plants and other animals. Eg : man | All green plants and some bacteria have autotrophic nutrition. Eg : animals like blue green algae, euglena have autotrophic nutrition, and plants like mango tree,neem tree etc. |
