Pyramid of Numbers
An ecological pyramid of numbers shows graphically the population of each level in a food chain.
The diagram to the right shows a (nonfictional) example of a five level pyramid of numbers: 10,000 fresh water shrimps support 1,000 bleak, which in turn support 100 perches followed by 10 northern pikes and finally one osprey.

Famous quotes containing the words pyramid and/or numbers:
“So universal and widely related is any transcendent moral greatness, and so nearly identical with greatness everywhere and in every age,—as a pyramid contracts the nearer you approach its apex,—that, when I look over my commonplace-book of poetry, I find that the best of it is oftenest applicable, in part or wholly, to the case of Captain Brown.”
—Henry David Thoreau (1817–1862)
“Old age equalizes—we are aware that what is happening to us has happened to untold numbers from the beginning of time. When we are young we act as if we were the first young people in the world.”
—Eric Hoffer (1902–1983)
