Trophic Pyramid Or Energy Pyramid

TROPHIC PYRAMID OR ENERGY PYRAMID
An ecological pyramid (also trophic pyramid or energy pyramid) is a graphical representation designed to show the biomass or biomass productivity at each trophiclevel in a given ecosystem.
Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivoresthat eat herbivores, then carnivores that eat those carnivores, and so on). The highest level is the top of the food chain.
Una pirámide ecológica (también pirámide trófica o pirámide de energía) es unarepresentación gráfica que permita conocer la biomasa o productividad de la biomasa en cada nivel trófico en un ecosistema determinado.
Pirámides ecológicas comienzan con los productores en la parteinferior (como las plantas) y proceder a través de los distintos niveles tróficos (como los herbívoros que se alimentan de plantas, entonces carnívoros que se alimentan de los herbívoros, carnívorosque se alimentan luego los carnívoros, y así sucesivamente). El nivel más alto es la cima de la cadena alimenticia.
Transfer of energy between trophic levels
Food chains and food webs
Energy is used toproduce new cells / remains fixed in that organism
Energy is passed on to the next trophic level through feeding
Producers are photoautotrophs (plants)
Transduce light energy into chemical P.E. byforming new tissues and storing organic compounds
(starch, glucose, lipids, proteins)
Consumers are herbivores, carnivores and omnivores
Decomposers are detritivores and saprophytes
Break down deadcomplex organic molecules into simple inorganic molecules
Food chains are feeding relationships and linked with each other to form complex food webs
Some organisms feed on different trophic levels /leaves and insects
Some organisms feed on different foods when they are larvae (leaves) and when they are adult (nectar produced by different flowers)
