An ecological pyramid is a graphical representation of the relationship between the different living organisms at different trophic levels. Charles Elton developed the concept of the pyramid of numbers. Later, G. Evylen Hutchinson and Raymond Lindeman developed the idea of the pyramid of energy or productivity. It can be observed that these pyramids are in the shape of actual pyramids, with the base being the broadest, which is covered by the lowest trophic level, i. The next level is occupied by the next trophic level, i. All the calculations for construction of these types of ecological pyramids must take into account all the organisms in a particular trophic level because a sample space of a few numbers or a few species will end up giving a huge level of errors. In this type of ecological pyramid, the number of organisms in each trophic level is considered as a level in the pyramid. The pyramid of numbers is usually upright except for some situations like that of the detritus food chain, where many organisms feed on one dead plant or animal. In this particular type of ecological pyramid, each level takes into account the amount of biomass produced by each trophic level.

Which of the following ecological pyramids is generally inverted

Ecological pyramids -. The number, biomass and energy of organisms gradually decrease from the producer level to the consumer level. This can be represented in the form of a pyramid called ecological pyramid. Ecological pyramid is the graphic representation of the number, biomass, and energy of the successive trophic levels of an ecosystem. Pyramid of biomass in sea is generally inverted. This is because the producers are tiny phytoplanktons that have negligible biomass as compared to the organisms at the higher trophic levels. Dont't have an account? Register Now.
