Question

Members of ‘heterotroph’ components are called:
A. Producers
B. Consumers
C. Decomposers
D. Autotrophs

Answer 1

Hint: An organism that cannot produce its own food, instead it takes nutrition from other sources of organic carbon, which are mainly plant or animal matter are called heterotrophs. Heterotrophs are primary, secondary and tertiary consumers, but not producers in the food chain. Heterotrophic living organisms include all animals and fungi, some protists and bacteria, many types of parasitic plants.

Complete answer:
Option A Producers: These are the organisms that make their own food. They are also known as autotrophs. Autotrophs get energy from the sun or chemicals, and with the help of water, they convert that energy into the form of sugar, or food which can be used later as usable energy.
Hence option A is not correct.
Option B Consumers: Those organisms that feed on other organisms to obtain their energy are known as consumers or heterotrophs. Heterotrophs do not manufacture their own food. Animals and birds are the commonly known consumers but there are also lesser-known ones, such as fungi.
Hence option B is the correct answer.
Option C Decomposers: Organisms that break down other dead and decaying organisms are known as Decomposers. These organisms carry out the process of decomposition, a process which is possible by only certain kingdoms, such as fungi.
Hence option C is not correct.
Option D Autotrophs: Also known as producers, these organisms can produce its own food using light, water, carbon dioxide, or other chemicals.
Hence option D is also not correct.

Hence, Option B. Consumers are the correct answer.

Note:
Primary, secondary, tertiary, and quaternary are the four categories of consumers. Food source within a specific food chain or food web defines the category in which an animal is suited, and not necessarily by its species or habits. A single species might be placed in different categories, depending on the availability of food sources. An organism does not necessarily need to be carnivorous to be a consumer.
