… However, between the stage of the primary producer (grain) to the cattle (herbivore), 90% of the energy supplied by the grain is lost in the raising of the cows. From the cattle to the humans, the same efficiency also holds; just 10% of the energy stored in the beef is passed on to people. But if the grain were directly fed to people, the amount of energy that would have been used (and wasted) by cattle would be used by people, essentially “saving” a great deal of available energy and biomass. This concept is particularly important in…Learn more>>

By Hannah Waters | July 26, 2011

…where would you stick a parasite in a pyramid of numbers? Feather lice, for example, live in the feathers of birds. If they are sucking the blood of a hawk, does that make them higher on the food chain than the hawk? Are they at a greater trophic level, despite being as small as they are? Does parasitism count as predation?…

Ecosystems have a carrying capacity, the maximum biomass each trophic level can support given finite resources. Here’s the pattern….


BIOMASS- PYRAMID GREEN TRIANGLE   The name of the pyramid biomass comes from the fact that it is represented in the pyramid form. Their energy capacity is usually concentrated at the base, which is represented as being wide and decreases as one move up to the apex. The pyramid is used as a manner of clarifying the movement of the biomass as well as the energy through the ecosystem…Learn more>>




renewable-button  Biomass vs. Energy Pyramids
 by Ellie Maclin | Updated April 25, 2017

Biomass pyramids and energy pyramids are two types of ecological “infographics” used by scientists to represent the relationships among elements in a food chain. Scientists can use these kinds of biological pyramids to determine the health of plant and animal populations by using pictures to represent concrete measurements of an ecosystem’s parts….



Upright And Inverted Pyramids?

Definition- Biomass pyramids are shaped that way to show that biomass is largest at the base, and decreasing in amount as it goes through the apex. The two types of biomass pyramids are the upright and the inverted. The upright pyramid is found in most ecosystems. It results when the combined weight of producers is larger than the combined weight of consumers. An inverted type results when the combined weight of producers is smaller than the combined weight of consumers.

Ecological Pyramids Are Of Three General Types Namely:
(i) Pyramid of numbers, showing the number of individual organisms at each level
(ii) Pyramid of biomass, showing the total dry weight and other suitable measure of the total amount of living matter, and
(iii) Pyramid of energy, showing the rate of energy flow and/or productivity at successive trophic levels.

…The pyramids of numbers and biomass may be upright or inverted depending upon the nature of the food chain in the particular ecosystem, whereas pyramids of energy are always upright…Learn more>>

Pyramid Of Energy
4 Functional Aspects Of An Ecosystem-  by Puja Mondal

Some of the important functions of an ecosystem are as follows:
– Energy flow in an ecosystem
– Food chain, food web and ecological pyramid
– Biogeochemical cycles
– Ecological succession.

(iii) Pyramid of Energy: The most ideal and fundamental method of representing the relationships between organisms in different trophic levels is the pyramid of energy. We know that in every ecosystem,…Learn more>>
