Pyramid of numbers : it represent the number of individual organisms at each trophic level. We may have upright or inverted pyramid of numbers, depending upon the type of ecosystem and food chain. A grassland ecosystem and a pond ecosystem show at applied pyramid of numbers. The producers in the grasslands are grass and that in a pond are phytoplankton (algae etc.), Which are small in size and very large in number. So, the producers form a broad base. The herbivores in grasslands are insects while tertiary carnivores are hawks or other birds which are gradually less and less in number and hence the pyramid apex becomes gradually narrower forming and upright pyramid. Similar is the case with the herbivorous, carnivorous and to...
