Given below is a pyramid of biomass in an ecosystem where each bar represents the standing crop available in the trophic level. With the help of an example explain the conditions where this kind of pyramid is possible in nature? 

Will the pyramid of energy be also of the same shape in the given trophic level situation? Give reason for your response.
