9. Which of the following best explains why the rock chimneys of the Lost City host such a variety of unique microbial communities?
a- The height of the chimneys creates a gradient of temperatures (hottest at the top and coolest at the bottom) along the chimney; these, in turn, become separate environments and host different communities.
b- The height of the chimneys creates a gradient of pH (most acidic at the top and most basic at the bottom) along the chimney; these, in turn, become separate environments and host different communities.
c- Although temperatures, pH, and other factors are the same all over each chimney, the chimneys are so big that different communities can occupy different sections of the chimney.
d- The Lost City comprises a huge number of rock chimneys, each of which has its own unique environment; this means that each chimney hosts its own unique microbial community.
e- None of the above.
