Tom Clements What is Bernoulli's Principle? Give examples of its diverse 'use' or 'exploitation' in animals. All living organisms inhabit a world governed by mechanical laws and processes. For all organisms, too, the primary daily task is the search for food. This is not only limited in quantity but can also be energetically costly to obtain. As a result many animals have evolved ways of harnessing these mechanical processes to assist them in performing tasks which would otherwise require the expenditure of chemical energy. In the world of energy economy these adaptations can prove crucial to survival. The major form of mechanical energy that exists is expressed in the form of flows (air and water currents driven by the sun). When these fluids flow across a solid surface (such as the ground or an animal's body) the velocity difference can be converted into useful forms of energy. This energy can either...
