Question

Difference Between Autotrophic And Heterotrophic Nutrition Class 10 Ncert

Answer 1

Answer:

Autotrophic nutrition

Autotrophic nutrition is the mode of nutrition whereby a living organism is able to create/produce its own food. Green plants and some types of bacteria are usually considered as a good example of autotrophs. They can synthesize inside their cells organic food such as starch, sugar, fats and proteins. They do this with the help of carbon dioxide and water in the presence of sunlight. Examples of autotrophs include:

Plants

Algae-Green algae and red algae

Bacteria such as cyanobacteria

Heterotrophic mode of nutrition is the mode of nutrition whereby a living organism cannot create/produce their own food. They are dependent on green plants or animals for their food. All the non green plants and animals inclusive of human beings are usually categorized as heterotrophs.

The non-green plants such as fungi, yeast, mushroom and bread mold lack chlorophyll which is necessary to carry out the process of food synthesis referred to as photosynthesis. When compared to autotrophs which occupy the base of the food web, heterotrophs occupy the upper levels of the food web given that their existence is dependent on the producers (autotrophs). More examples of heterotrophs include:

Ants

Tiger

Lion

Dogs

Cats

Buffalo

Mosquitoes

Cows

Snakes

Answer 2

Answer:

autotrophic are organism that can produce their own food from the substance available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). heterotrophic cannot synthesize their own food and rely on other organisms
