what is autrophs and heterotrophs
Answers
Explanation:
Food is the only source of energy for all living organisms on this planet. This food is available from different sources. Living organisms are further divided based on the modes of nutrition:
Autotrophs
Heterotrophs
Here in this article, let us know about the differences between autotrophs and heterotrophs, along with the examples.
Difference between Autotrophs and Heterotrophs
The differences between autotrophs and heterotrophs are given below:
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.
