Answer» Answer: Explanation: PICTORIAL representation to represent the relation between trophic levels in an ecosystem on the basis of biomass,number ,and energy. concept introduced by charles elton and hence KNOWN as eltonian pyramids. base represent producers and are broader [exceptions are there]. 1)biomass =biomass of different organism present in different trophical level. inverted biomass pyramids present in aquatic ecosystem. 2)number=number of members ,inverted in case of a tree ecosystem. 3)energy =based on the AMOUNT of energy transfered ONTO each trophic level ,follow 10% law and hence only 10% of energy present in ONE level is transfered into the next level.AND HENCE WILL ALWAYS BE AN UPRIGHT PYRAMID ,NOT AN INVERTED ONE. |
