Question

write any two difference between autotrophic and heterotrophic mode of nutrition​

Answer 1

Answer:

Autotrophs are producers which prepare their own food

Heterotrophs are the consumers who depend on other sources for their food.

Answer 2

Answer:

Difference between Autotrophs and Heterotrophs

The differences between autotrophs and heterotrophs are given below:

Autotrophs Heterotrophs

Type of Organisms-----

Autotroph ---Usually members of the plant kingdom and certain unicellular organisms like cyanobacteria

Heterotroph ---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----

Autotroph ----These can be classified as photoautotrophs and chemoautotrophs.

Heterotroph---- These can be classified as photoheterotrophs and chemoheterotrophs.

Presence of chloroplasts----

Autotroph-----The chloroplast helps in preparing food.

Heterotroph----They do not contain chloroplast, so cannot prepare food

Energy is obtained from-----

Aututroph---They obtain energy from inorganic sources by converting light energy into chemical energy.

Heterotroph---- 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----

Autotroph----- They are placed at the primary level in the food chain.

Heterotroph---- These are placed in the secondary or tertiary level in the food chain.

Locomotion-----

Autotroph--- They cannot move from their place. Heterotroph---- Can move from one place to another in search of food and shelter.

Examples-----

Autotrophs--- Green plants, algae and a few photosynthetic bacteria are examples of autotrophs.

Heterotrophs--- Cows, buffaloes, tigers, horses, humans are examples of heterotrophs.
