The Pyramid of Numbers

Now you are well aware of the fact that there is a reduction in the number of organisms when entering one trophic level to the other. The schematic representation based on the number of organisms at each trophic level is then called the pyramid of numbers. The lower part of the pyramid is represented by the green plants in the food chain and its upper part is represented by the higher levels of carnivores.

Demonstrate and examine the different trophic levels of a food chain based on their numbers. Examine whether the representation is in the form of a pyramid.
