Why is the pyramid of biomass always inverted in shape in a pond ecosystem and pyramid of energy in an ecosystem always?
The inverted shape of the pyramid of biomass in a pond ecosystem and the upright shape of the pyramid of energy in any ecosystem are both related to the fundamental principles of energy flow and ecological efficiency within the food chain.
The inverted shape of the pyramid of biomass in a pond ecosystem is due to factors such as rapid reproduction of primary producers and fast turnover rates of herbivores, while the upright shape of the pyramid of energy in any ecosystem is a consequence of the inefficiency of energy transfer and the limiting biomass at higher trophic levels.
In a pond, as the producers are small organisms, their biomass is least, and this value gradually shows an increase towards the apex of the pyramid, thus making the pyramid inverted in shape. A pyramid of biomass represents the mass of organisms at each trophic level. A pyramid of biomass is always shaped like a pyramid because the biomass always goes down from one trophic level to the next. This is an Arctic food chain. The pyramid of biomass in sea is also generally inverted because the biomass of fishes far exceeds that of phytoplankton. The pyramid of biomass may be "inverted". As, in a pond ecosystem, the standing crop of phytoplankton, the major producers, at any given point will be lower than the mass of the heterotrophs, such as fish and insects. Other ecological pyramids such as pyramids of number and pyramids of biomass in the pond ecosystem are always inverted because, in the ponds the number and biomass of the consumers are more in number than the producers. Other ecological pyramids such as pyramids of number and pyramids of biomass in the pond ecosystem are always inverted because, in the ponds the number and biomass of the consumers are more in number than the producers. Pyramid of energy is always upright. This is because during energy transfer between adjacent trophic levels, energy is lost in the form of heat. Pyramid of energy is always upright. As energy flows from one trophic level to the next trophic level some amount of energy is lost in each trophic level in the form of heat. Therefore, the pyramid of energy is always upright and can never be inverted. Pyramid of energy is always upright. As energy flows from one trophic level to the next trophic level some amount of energy is lost in each trophic level in the form of heat. Therefore, the pyramid of energy is always upright and can never be inverted. In the aquatic ecosystem, the main producers are diatoms and phytoplanktons which have high annual productivity but their life span is short that's why it is less than than the primary consumers. Hence the pyramids which get formed are inverted or spindle-shaped.
