What are the three common patterns of population distribution? what might cause a population to disperse in an evenly spaced pattern?

Uniform, Clumped, and Random are the three common patterns of population distribution.  Food supply and resources are directly proportional to a particular distribution pattern. Random distribution occurs when several pollen grains of some flowers were carried by wind or bees. These flowers will then bloom where they were scattered.

H=   2(area/a+b)h= 2(144/a+b)h= 2(144/18+18)h= 2(144/36)h= 2(4)h=8
