Write a note on the producers, consumers and decomposers of the biotic environment with examples of each.
Answers
Answer:
Producers: Those organisms which produce food by photosynthesis, i.e. organisms which can make organic compounds like sugar and starch from inorganic substances using the radiant energy of the sun in the presence of chlorophyll. Producers, therefore are considered as a source of energy for those above it in a food chain. Examples: All green plants also called autotrophs and certain blue-green algae. Consumers: Those organisms which depend upon the producers for food, either directly or indirectly by feeding on other consumers for their sustenance. Consumers, therefore, feed upon those below it in a food chain and are called heterotrophs. These can be classified into primary consumers or herbivores, secondary consumers or small carnivores, omnivores and parasites, e.g. cows, humans. Examples of consumers: Herbivores are the animals that consume or eat vegetation or plants, e.g. cows, horses. Carnivores are the animals that eat flesh of other animals, e.g. tigers, wolves. Omnivores are the animals that eat both plants and animals, e.g. humans, cockroaches. Parasites are those organisms that live on (ectoparasites) or in (endoparasites), the body of another organism, i.e. host from which it obtains its nutrients, e.g. parasites of man includes fleas and lice (ectoparasites), various protozoans and tapeworms. (endoparasites) Decomposers: They are those microorganisms that obtain energy from the chemical breakdown of dead organisms or animal or plant wastes. These microorganisms are the decomposers as they breakdown the complex organic substances into simple inorganic substances that enter into the soil and are again used up by the plants. Examples: Bacteria and fungi
