write down difference between autotrophic and heterotrophic nutrition
Answers
Autotrophs:
Autotrophs are organisms that undergo autotrophic mode of nutrition. These are the organisms that can prepare their own food from simple substances like carbon dioxide and water. All green plants are examples of autotrophs. These green plants contain chlorophyll pigment in the plant cell that helps in the synthesis of their own food by absorbing energy from the sunlight. All autotrophs are producers and are placed at the primary level in the food web.
Carbohydrates can be converted to fatty acids to produce lipids. Other elements may be added to synthesize organic compounds such as proteins. Carbohydrates, proteins and lipids can be used as energy sources during respiration by both autotrophs and heterotrophs, recycling carbon dioxide so that it may again be used in photosynthesis.
Heterotrophs :
Heterotrophs are organisms which cannot prepare their own food and depend upon producers or green plants and other animals for their food. This mode of nutrition is known as the heterotrophic mode of nutrition.
Heterotrophs rely on autotrophs to provide a continuous supply of new organic molecules. Heterotrophs are considered as consumers in the food web and are placed at a secondary or tertiary level.
All the non-green plants and animals, inclusive of human beings, are the best examples of heterotrophs.
The heterotrophs are benefited from photosynthesis in many ways. Directly by consuming plants as herbivores
Indirectly by attacking, killing and consuming other herbivores animals (carnivores) or both animals and plants (omnivores). By using oxygen for the cellular respiration process.

Answer:
Autotrophic nutrition , an organism that do not depend on each other for food it make their own food ,mainly green plants are autotrophic nutrition organism who make their own food by the process of photosynthesis.
Where as hetrotrophic nutrition, an organism that depend on each other for food, like
all organism except green plants.
