Can anyone please help me complete the dichotomous key attached on pg #103 for figures 1-8 on pg #102 (it is in the pdf of the textbook)?

not too sure but maybe in the hot springs.

i think i can answer even without the example. over time with environmental changes, sometimes a group of animals will adapt to better survive. take a moth for example. if the trees the moths use to camouflage themselves from predators, started to die or change colors themselves, the moths may, overtime of course, change color too. its just adapting to its surroundings. hope i was of any : )
