Question 9 1 pts Which of the following statements about the relationship between elevation and species richness are true (Select all that apply)? Species richness peaks generally at intermediate elevations Each family's species richness peaks at a different elevation Species richness peaks generally at the highest elevation Species richness is always lowest at low elevations Question 10 1 pts One might speculate that elevational gradients and latitudinal gradients should be similar if temperature is the underlying important variable, since it is colder at higher elevations. Is the elevational gradient for these frog species similar to the expected latitudinal gradient? True False

Which of the following represents an example of habitat suitability as an explanation of species abundance and distribution? Group of answer choices (select all that apply) Two closely related species of frogs have overlapping ranges and isolated on a single mountain. As temperatures increase, tropical species are expanding their geographical range as more regions have preferred temperatures. Darwin's finches are only found on the Galapagos islands because of dispersal limitations.

The latitudinal diversity gradient refers to what pattern of species diversity? A) For many kinds of organisms, species diversity is greatest near the equator and lowest near the poles. B) For many kinds of organisms, species diversity is greatest near the poles and lowest near the equator. C) For many kinds of organisms, species diversity is greatest at low elevation and lowest at high elevation. D) For many kinds of organisms, species diversity is greatest at high elevation and lowest at low elevation. E) Plants are most diverse near the equator while animals are most diverse toward the poles.
