Which statement about organisms' "niche" is false? The niche summarizes environmental factors influencing growth, survival, and reproduction of a species The "fundamental" niche refers to physical, but not biological, aspects of the environment Interactions such as competition and parasitism may restrict the size of an organism's niche In the laboratory, two species with identical niches are especially easy to maintain in a mixed culture Which of the following is NOT a population characteristic favored by K-selection? low intrinsic rate of increase late reproduction many, small offspring repeated bouts of reproduction strong competitive ability Which of the factors can stabilize predator-prey relationships by providing a prey refuge? An area of prey habitat that is isolated and difficult for predators to find The occurrence of prey in numbers too large for predators to attack effectively The ability of prey to grow to a size invulnerable to predation All of the above The "trophic cascade hypothesis" emphasizes the role of nutrients in controlling primary productivity nutrients in controlling primary consumption consumers in controlling primary productivity grazing by herbivores in controlling ecosystem nutrient levels primary productivity in controlling primary and secondary consumption The Lotka-Volterra predation model predicts that predators and prey, living together, will show oscillations in population size that increase in amplitude through time oscillations in population size that remain of constant amplitude through time oscillations in population size that decrease in amplitude through time oscillations, but only when outside forces such as climatic variation are also present steady equilibria in population sizes
