Question

difference between autotrophic and heterotrophic 6 points

Answer 1

1.Autotrophsare organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis).
2.Autotrophs use inorganic materials like carbon dioxide, water, Sunlight to create their own food.
3.Autotrophs use colouring pigments like chlorophyll in the process of photosynthesis to produce food.
4.EXAMPLESAutotrophs are mainly green plants
5.Autotrophic nutrition is influenced by biochemical catalytic substances, water, humidity, temperature, etc.




1.Heterotroph are the organisms which are dependent on other organisms for their food.
2.Heterotrophs procure food by feeding on other organisms directly or indirectly.
3.Heterotrophs don’t need any coloring pigments to obtain food.
4.Heterotrophs are also called as parasites and some examples are animals, birds, fungi, some Protozoa, etc.
5.Heterotrophic nutrition is influenced by digestive enzymes, Nature of food what is vegetarian or non-vegetarian, etc.

Answer 2

Hello Friends,

◆ Autotrophic vs heterotrophic nutrition -

• In autotrophic nutrition, organisms produce their own food while no such thing is possible in heterotrophic nutrition.
• Autotrophs are primary producers while heterotrophs are consumers.
• Autotrophs food production is independent whereas heterotrophs are directly/independently dependent on autotrophs for food.
• Autotrophs use raw matetials like CO2, water, minerals to prepare food while heterotrophs consume readymade food for nutrition.
• Autotrophs include plants, algae & bacteria while heterotrophs include fungi & animals.

Hope this helped.
