Frequently Asked Questions

• What do you mean by an ecological pyramid?

  What is Ecological Pyramid? An ecological pyramid is a graphical representation of the relationship between the different living organisms at different trophic levels.

• Who are the producers in an ecological pyramid?

  Ecological Pyramid. Producers are at the lowest level. Just as in a food chain, the producers are consumed by the primary consumers, in an ecological pyramid; the next level is occupied by the primary consumers. The next level of the pyramid is occupied by the secondary consumers and the last, by the tertiary consumers.

• Where does energy move in an ecological pyramid?

  In the pyramid, energy moves in the upward direction initiated by the primary producers or autotrophs which includes plants and algae. Primary producers are present at the bottom of the pyramid. On top of this are the primary consumers who eat the primary producers.

• Why are saprophytes not included in an ecological pyramid?

  Moreover, saprophytes (plant, fungus, or microorganism that lives on decaying matter) are not given any place in ecological pyramids even though they play a vital role in the ecosystem. Pollutants move through the various trophic levels in an ecosystem.

• What are the limitations of an ecological pyramid?

  In this article we will discuss about ecological pyramids an its limitations. These are the diagrammatic illustrations of connection between different trophic levels in terms of energy, biomass and number of an organism. The base of each pyramid represents the producers or the first trophic level.

• How is the flow of energy shown in an ecological pyramid?

  The pyramid ideally shows who is consumed by whom, while also showing the order in which the energy flows. The flow of energy in an ecological pyramid is from bottom to top, which means energy from the autotrophs, who are also the primary producers, goes to the primary consumers, meaning those who consume these plants.

• How are ecological pyramids related to food chains?

  Ecological pyramids are graphical representations of relationship between the different trophic levels of food chains on the basis of energy, number and biomass 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.e., producers.

• Which is the best description of a pyramid of energy?

  Pyramid of Energy To compare the functional roles of the trophic levels in an ecosystem, an energy pyramid is most suitable. An energy pyramid represents the amount of energy at each trophic level and loss of energy at each transfer to another trophic level. Hence the pyramid is always upward, with a large energy base at the bottom.
