Jim's grandmother was hospitalized recently and jim was surprised to see "anorexia" on her list of diagnoses. he asked the attending physician if his grandmother had an eating disorder, and the physician explained the difference between "anorexia" and "anorexia nervosa." what does the word "anorexia" mean?

The word anorexia can be directly translated into without appetite. The word’s etymology is derived from the Greek works an meaning without and the Greek word orexis meaning appetite. It also can be directly translated from Modern Latin that means morbid want of appetite. 

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
