Explain how the surface tension of water is important in the biological world

Surface tension an important compound, water. This is because "Normal" water at ambient temperature has a high surface tension, but the addition of different chemicals can alter this. The relationship between the molecules affects the fluidity of the liquid and it's ability to support pressure. So basically, because of the element of surface tension water is able to function the way it does and support our needs the way we need it to.
