Question

What are organisms that make their own food called?

Answer 1

Hint: The mode of nutrition in living organisms are divided into autotrophic and heterotrophic depending upon the way they obtain their food from organic or inorganic raw materials and the name these organisms are autotrophs or heterotrophs.

Complete answer:
The organisms that make their food are called Autotrophs. The autotrophic organisms are divided into photosynthetic and chemosynthetic. The photoautotrophs consume solar energy and convert the inorganic raw material to organic food by photosynthesis. The chlorophyll present in the plant helps in the photosynthesis process by trapping the solar energy. Photosynthesis is of two types: anoxygenic in bacteria and oxygenic in green protists and plants.
In a chemosynthetic organism, the organic food gets prepared by the chemical reactions because of the absence of photosynthetic pigment and this type of nutrition shown by some bacteria.

Additional information:
Heterotrophic organisms are of two types: ingestive and absorptive. The ingestive organisms absorb food in solid form whereas the absorptive organisms absorb food in liquid form like saprozoic, saprophytic and parasitic. The liquid form of food gets to obtain from the dead organic matter like from dead plants and animals. The hypertrophic animals are consumers from the second trophic level to the last trophic level.

Note:
The autotrophic mode of nutrition is also known as holophytic nutrition. The photosynthetic organisms in the environment work as a producer as they produce food for a higher level of organisms. Insectivorous plants act as both autotrophs and heterotrophs because instead of showing photosynthesis they trap insects to fulfill the nitrogen deficiency as they grow in nitrogen-deficient areas.
