##### PART 1Community ecologists draw "food webs" to describe the predatorand prey relationships between all organisms living in an area. Atheoretical model predicts that a measure of the structure of foodwebs called "diet discontinuity" should be zero. Diet discontinuityis a measure of the relative numbers of predators whose prey arenot ordered contiguously. Researchers have measured discontinuityscores for seven different food webs in nature. The values are:0.35, 0.08, 0.004, 0.0
