Types of Ecological Pyramids
The ecological pyramids may be of following three kinds. 1. Pyramid of Number: It depicts the number of individual organisms at different trophic levels of food chain. This pyramid was advanced by Charles Elton (1927), who pointed out the great difference in the number of the organisms involved in each step of the food chain.
Read this article to learn about the major types of ecological pyramids: pyramid of number, biomass and energy: A pyramid-shaped diagram representing quantitatively the numbers of organisms, energy relationships, and biomass of an ecosystem; numbers are high for the lowest trophic levels (plants) and. low for the highest trophic level. Since some energy is lost as heat, in each transformation. This relationship is sometimes called ecological pyramid.

In many ecological pyramids, the producer form the base and the successive trophic levels make up the apex. The ecological pyramids may be of following three kinds. 1. Pyramid of Number: It depicts the number of individual organisms at different trophic levels of food chain.
