3) One species of aquatic plant lives at the edge of wetland habitats in very shallow water that occasionally dries, while another species is found only in deep-water habitats that never dry. A) which species likely has a wider "physiological tolerance" for abiotic factors (said another way, a larger fundamental niche). B) abiotic factors in the deeper habitat are within the tolerance range of the shallow water species, why isn't the shallow species found in high numbers in the deeper-water habitat? Use natural selection to argue why you usually wouldn't expect species to have exactly the same physiological tolerances or exactly the same distribution. C) which species likely has a larger geographic range? Why? D) which species is probably a better overall competitor? Why? 4) An underlying theme of physiological ecology is adaptation of organisms to their local environments. But these adaptations shouldn't be viewed as an optimal fit of species to their environment. In fact, over geological time, nearly all species have gone extinct. Discuss why this is the case. Why cant natural selection "prevent" species extinctions? 5) Use optimal foraging theory to explain the widespread love of fatty foods in humans. 6) In your own words, explain the relevance of the saying "a jack of all trades is a master of none" to the field of ecology. .
