Pyramid of numbers

Pyramid of numbers.png
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.
