Question

Distinguish between biotic and abiotic environments with examples ?

Answer 1

Hint - The world of living organisms is known as the biological environment. Examples are Plants and Animals. The world of the inanimate element is known as the abiotic environment such as land.

Complete answer - The biotic factor or biotic component is the living organism that shapes an ecosystem. Biological factors include plants, animals, bacteria, algae and all other living forms present in an ecosystem. An ecosystem is a complex system of living and non-living things; The living part of the system forms biotic factors. Biological factors include all producers, consumers and decomposers involved in the transformation and transport of energy through the food cycle. These biotic factors are also responsible for diseases and outbreaks. Producers are groups of organisms that make their food through processes such as photosynthesis.

BioticAll those resources which are obtained from the biosphere and have life are known as biotic resources.It is classified among producer, consumer and decomposer.Forest, human beings and livestocks are examples of Biotic.

AbioticAll those resources which are composed of non living things are called abiotic resources.It is classified between renewable and non renewable.Light, soli, water and rain are examples of abiotic.

Most manufacturers use photosynthesis to convert solar energy into chemical energy, but various autotrophs also use phototrophy and other processes like chemistry. All green plants have chlorophyll as the photosynthetic pigment for the process of photosynthesis. Other pigments such as bacterial rhodopsin and carotenoids are also found in some bacteria, algae, and phytoplankton for photosynthesis. Some producers produce food by the process of chemistry, which derives energy from chemical reactions rather than from sunlight.
Consumers are groups of organisms that feed producers directly or indirectly for energy and food. Consumers, as primary and secondary consumers, live in different trophic levels. Primary consumers are vegetarians who directly depend on autotrophs or producers. Secondary consumers, in turn, feed primary consumers. Biological factors of the ecosystem are responsible for capturing energy for the conversion of inorganic compounds into organic compounds. Biotic factors, along with abiotic factors, determine the nature of ecosystems and ecological niches.


Note - Man is one of the most important biological factors that affect the state of the environment and the existence of other living beings. As a result of various technological advances, humans have significantly changed the global ecosystem along with other naturally occurring climate changes. The most obvious example of this is the impact of human activities on the carbon cycle. As a result of growing industries and automobiles, large amounts of carbon dioxide and carbon monoxide are being emitted, which directly affect the world's climatic conditions and air quality. Other activities such as deforestation and urbanization have brought about massive changes in the quantity and quality of soil, land and water. These changes lead to rapid climate change leading to mass extinction of many organisms. Therefore, humans act as the most powerful biotic factors of any ecosystem.
