The three types of trophic pyramids studied in ecology are the numeric pyramid, the biomass pyramid and the energy pyramid. Generally, the variable dimension of the pyramid is the width, and the height is always the same for each represented strata of living organisms. The width therefore represents the number of ...
It is a graphical representation or pyramid shaped diagram which depicts the number of organisms, biomass and productivity at each trophic level. Ecological pyramids begin with the producers at the bottom and proceed through the different trophic level.
Upright pyramid of number: It is found in the aquatic and grassland ecosystem, in these ecosystems, there are many small autotrophs which support lesser herbivores which in turn support the smaller number of carnivores. So, the pyramid is upright. The inverted pyramid of number; It is seen in the parasitic food chain where ...

Diagram showing the relationship of biomass to trophic levels a) Why do food chains usually only have four (and at the most five) trophic ...
Likewise, the ecosystem of a pond will also yield an upright pyramid. The phytoplankton makes up the base of the pyramid as the main producers in maximum numbers. These are followed by the herbivores such as small fish rotifers that serve as food for the secondary consumers. At the top of the pyramid of numbers, there ...

Here is our Java program to draw the pyramid pattern as shown in the problem statement. In this program, we have two examples of printing pyramid, in first we have printed pyramid of star character, while, in the second example, we have drawn a pyramid of numbers. The key here is to use both print() and println() method ...
