Question : The organisms deriving their energy from the same energy source are grouped in same trophic level, while a series of trophic levels showing repeating eating and eaten by is called a food chain. These food chains may be predatory or parasitic or saprophytic chains. In an ecosystem , no food chain is independent . Different food chains are interlinked to form a network called food web. The food webs operate in both aquatic as well as terrestrial ecosystems . Answer the following equations on food chains and food webs : Why do the organisms of a higher torphic level have less energy available than those of a lower trophic level ?

Question : The organisms deriving their energy from the same energy source are grouped in same trophic level, while a series of trophic levels showing repeating eating and eaten by is called a food chain. These food chains may be predatory or parasitic or saprophytic chains. In an ecosystem , no food chain is independent . Different food chains are interlinked to form a network called food web. The food webs operate in both aquatic as well as terrestrial ecosystems . Answer the following equations on food chains and food webs : Why do the organisms of a higher torphic level have less energy available than those of a lower trophic level ?
Answer» Solution :Because during energy transfer from LOWER to HIGHER TROPHIC LEVEL, about 90% of energy is lost at each transfer.
