When the number of organisms at successive levels are plotted, they assume the shape of a pyramid. This is called the pyramid of?
Answers
Explanation:
A pyramid of numbers is a graphical representation that shows the number of organisms at each trophic level. It is an upright pyramid in light of the fact that in an ecosystem, the producers are always more in number than other trophic levels.
The pyramid of numbers was advanced by Charles Elton in 1927. Charles pointed out the huge difference in the number of organisms involved in each level of the food chain. Succeeding links of the trophic structure reduce rapidly in number until there’s a very small number of carnivores at the top.
The reason for the pyramid shape is that there must always be enough plants to produce food at the bottom. Otherwise, the entire food chain would collapse. At the higher level, no predator can be as common as its prey. Otherwise, the population of both animals would soon be wiped out. Sparrowhawks, for example, can never be common than blue tits if they live in the same ecosystem.
