What limiting factor appears to determine the carrying capacity of kelp in a marine ecosystem that is based on this food chain? How can you tell?

(If you guys can answer the other question that would be great too!!)

Well, the environmental resistance is the combination of all factors that act to limit the growth of a population. It largely determines an area's carrying capacity: the maximum population of a given species that a particular habitat can sustain indefinitely.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
