- Figure 19.6 If the major food source of seals declines due to pollution or overfishing, which of the following would likely occur? a. The carrying capacity of seals would decrease, as would the seal population. b. The carrying capacity of seals would decrease, but the seal population would remain the same. c. The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d. The carrying capacity of seals would remain the same, but the population of seals would decrease.Figure 45.10b If the major food source of the seals declines due to pollution or overfishing, which of the following would likely occur? The carrying capacity of seals would decrease, as would the seal population. The carrying capacity of seals would decrease, but the seal population would remain the same.

Expand on these points individually, based on your species’ unique story. Domino Effects As we’ve learned, species are not islands unto themselves; they are integrated with many other organisms in trophic relationships, mutualisms, competition, etc. How is the absence of this species (or its lowered population size) likely to impact the other members of its habitat? (If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.) Conservation Efforts Discuss past, current, and proposed efforts to conserve this species. Are these strategies effective? Are they realistic? What is the outlook for this organism?
