Write a note on the producers, consumers and decomposers of the biotic environment with examples of
each.
Answers
At any given point of time do you find yourself to be surrounded by nature, with all its beauty in the form of trees, plants, lakes, rivers, animals, insects etc.? Do you think there is some form of contact or collaboration between the living and the nonliving components of ecosystem
Biotic Components of Ecosystem
The living components of an ecosystem are called the biotic components. Some of these factors include plants, animals, as well as fungi and bacteria. These biotic components can be further classified, based on the energy requirement source. Producers, consumers, and decomposers are the three broad categories of biotic components.
Producers are the plants in the ecosystem, which can generate their own energy requirement through photosynthesis, in the presence of sunlight and chlorophyll. All other living beings are dependent on plants for their energy requirement of food as well as oxygen.
Consumers include herbivores, carnivores, and omnivores. The herbivores are the living organisms that feed on plants. Carnivores eat other living organisms. Omnivores are animals that can eat both plant and animal tissue.
Decomposers are the fungi and bacteria, which are the saprophytes. They feed on the decaying organic matter and convert this matter into nitrogen and carbon dioxide. The saprophytes play a vital role in recycling the nutrients so that the producers i.e. plants can use them once again.
Answer:
Yes! Here is your answer!
Explanation:
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.
