If you wanted to determine what factor influences a species’ lower limit in the rocky intertidal, what would be the best experimental set-up?

Because sea otters cannot conserve internal heat by having a thick layer of blubber, they must consume as much as a quarter of their body weight in food every day.

Based on the ‘Intermediate Disturbance Hypothesis’, one would expect that a community that only experiences disturbance very rarely would be dominated by K-selected species.

Q27-Q32: In the following 8 questions, choose “A”  if the statement applies best to planktotrophic larvae, or  “B” if the statement applies best to lecithotrophic larvae. Which would do best traveling in a current with an abundance of phytoplankton. 

Sea otters maintain their warm body temperature in the cold water in which their kelp forest ecosystem thrives by

One characteristic of all types of marine mammals is that they rely on a layer of  blubber to help them maintain their body temperature.
