Note on energy pyramid |
| Answer» <html><body><p>An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.A pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels. Energy pyramids are necessarily upright in healthy ecosystems, that is, there <a href="https://interviewquestions.tuteehub.com/tag/must-2185568" style="font-weight:bold;" target="_blank" title="Click to know more about MUST">MUST</a> always be more energy available at a given level of the pyramid to support the energy and biomass requirement of the next trophic level.A pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level, while a pyramid of biomass shows how much biomass (the <a href="https://interviewquestions.tuteehub.com/tag/amount-374803" style="font-weight:bold;" target="_blank" title="Click to know more about AMOUNT">AMOUNT</a> of living or organic matter <a href="https://interviewquestions.tuteehub.com/tag/present-1163722" style="font-weight:bold;" target="_blank" title="Click to know more about PRESENT">PRESENT</a> in an organism) is present in the organisms. There is also a pyramid of <a href="https://interviewquestions.tuteehub.com/tag/numbers-22758" style="font-weight:bold;" target="_blank" title="Click to know more about NUMBERS">NUMBERS</a> representing the number of individual organisms at each trophic level. Pyramids of energy are normally upright, but other pyramids can be inverted or take other shapes.Ecological pyramids <a href="https://interviewquestions.tuteehub.com/tag/begin-389976" style="font-weight:bold;" target="_blank" title="Click to know more about BEGIN">BEGIN</a> with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat flesh, then omnivores that eat both plants and flesh, and so on). The highest level is the top of the food chain.Biomass can be measured by a bomb calorimeter.</p></body></html> | |
