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.
