write differences between autotrophic and heterotrophic nutrition
Answers
Answer:
Autotrophs Heterotrophs
Type of Organisms
Usually members of the plant kingdom and certain unicellular organisms like cyanobacteria All members of the animal kingdom
Mode of Nutrition
Autotrophs are producers which prepare their own food. Heterotrophs are the consumers who depend on other sources for their food.
Classified into
These can be classified as photoautotrophs and chemoautotrophs. These can be classified as photoheterotrophs and chemoheterotrophs.
Presence of chloroplasts
The chloroplast helps in preparing food. They do not contain chloroplast, so cannot prepare food.
Energy is obtained from
They obtain energy from inorganic sources by converting light energy into chemical energy. They obtain energy directly or indirectly from other organisms.
Energy Storage
Autotrophs can store light energy and chemical energy. Heterotrophs cannot store energy.
In Food Chain
They are placed at the primary level in the food chain. These are placed in the secondary or tertiary level in the food chain.
Locomotion
They cannot move from their place. Can move from one place to another in search of food and shelter.
Examples
Green plants, algae and a few photosynthetic bacteria are examples of autotrophs. Cows, buffaloes, tigers, horses, humans are examples of heterotrophs.
Explanation:
Autotrophic nutrition is the mode of nutrition in which organisms make their own food from inorganic substance found in their surroundings such as carbon dioxide , water and sunlight
Heterotrophic nutrition is a mode of nutrition in which organisms depend on other organisms as their food. Heterotrophic nutrition is of three types:
parasitic nutrition: in which organisms get their food from another organisms called their host without killing them
holozoic Nutrition
saphrophytic nutrition
