- CA least tern ENDANGERED ANIMAL is CA least tern questionbases on the bird CA least term Reasons for Endangerment Explain the various factors that have led to this species’ current plight. 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?Which statments are correct? Question 25 options: Species diversity tends to increase with evapostranspiration Species diversity tends to increase with when parasitism is low Species diversity tends to increase with island area Species diversity tends to be higher when disturbance frequency is low Species diversity tends to increase with decreasing latitudeQuestion 1 Which dispersal mechanism is most likely for late successional plant species? O birds O wind O mammals bats A Moving to another question will save this response.

The annual temperatures (but not precipitation) are similar. The annual precipitation (but not temperature) is aimilar Both the annual temperatures and precipitation are aimilar None of the above is likely to be true.Of these choices, which best describes an organism's niche?
