0/1 points | Previous Answers SBioCalc1 7.4.053 My Notes 20. The number of species n found on islands typically increases with the area of the island A. Suppose that this relationship is such that the rate of increase with island area is always proportional to the density of species (that is, number of species per unit area) with a proportionality constant k between and 1. Find the function that describes the species-area relationship. (Let n(1) = n1.) n= X Need...
