Energy Card Pyramid, Jiten Pyracard Energy And Vitality

Energy Card Pyramid/Vitality Card Pyramid (ऊर्जा कार्ड पिरामिड) : Energy Card Pyramid is the most useful of the types, showing the direct relationship between energy and trophic level. This allows for organisms on the lower levels to maintain a stable population, but to also feed the organisms on higher trophic levels, thus transferring energy up the pyramid.- Vitality Card Pyramid

An Vitality Card Pyramid is a presentation of the trophic levels in an ecosystem. Energy from the sun is transferred through the ecosystem by passing through various trophic levels. Roughly 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels. There must be higher amounts of biomass at the bottom of the pyramid to support the energy and biomass requirements of the higher trophic levels. -Energy Card Pyramid.

A “pyramid of productivity” is often more useful, showing the production or turnover (the rate at which energy or mass is transferred from one trophic level to the next) of biomass at each trophic level. Instead of showing a single snapshot in time, productivity pyramids show the flow of energy through the food chain. Typical units are grams per meter2 per year or calories per meter2 per year. As with the others, this graph shows producers at the bottom and higher trophic levels on top. -Vitality Card Pyramid

The advantages of the Energy Card Pyramid of productivity as a representation:

• It takes account of the rate of production over a period of time.
• Two species of comparable biomass may have very different life spans. Thus a direct comparison of their total biomasses is misleading, but their productivity is directly comparable.
• The relative energy chain within an ecosystem can be compared using pyramids of energy; also different ecosystems can be compared.
• There are no inverted pyramids.
• The input of solar energy can be added.

Nonetheless, productivity pyramids usually provide more insight into an ecological community when the necessary information is available. -Energy Card Pyramid.
