Two species of leaf-eating lizards (species A and B) have coexisted on an isolated island for more than 10,000 years. In 1964, a third species of leaf-eating lizard (species C) was accidentally introduced by humans visiting the island. The graph below shows the population sizes of the three species since that time: Explain the pattern of population density observed in species C. Describe the effect that the introduction of species C had on both species A and B.

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i. e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
