Q.6 Describe types of Ecological Pyramids.<\/strong>
\nAnswer:<\/strong>
\nDefinition<\/strong>
\nEcological pyramid can be defined as, \u201cA representation of the number of individuals or amount of biomass or energy present in various trophic levels of a food chain”.
\nExplanation<\/strong>
\nIn 1927, Charles Elton (an English ecologist) developed the concept of ecological pyramids. He noted that the animals present at the beginning of food chain are abundant in number while the animals present at the end of food chain are fewer in number.
\nTypes of Pyramids <\/strong>
\nEcological pyramids are of three types:
\n1) Pyramid of Numbers <\/strong>
\nIt is the graphic representation of the number of individuals per unit area at various trophic levels of a food chain.
\nExample<\/strong>
\nUsually, producers are present in large number, primary consumers are in lesser number, and secondary consumers are fewer. So, the producers are of smallest size but maximum in number, while the tertiary consumers are larger in size but lesser in number.
\n\"pyramids\"
\n2) Pyramid of Biomass\u00a0<\/strong>
\nIt is the graphic representation of biomass present per unit area at various trophic levels of a food chain. Example<\/strong>
\nIn a terrestrial ecosystem, the maximum biomass is of producers and there is progressive decrease in biomass from lower to higher trophic levels.
\nBiomass<\/strong>
\nThe total amount of living or organic matter in an ecosystem at any time is called “biomass\u201d.
\n\"\"
\n3). Pyramid of Energy <\/strong>
\nIt is a graphic representation of energy present in a biomass of living organisms at various trophic levels of a food chain.
\nExample<\/strong>
\nThe amount of energy is decreased from producers to decomposers as some amount of energy is used by the organisms to perform work while some of it is lost.
