Is nuclear physics related to chemistry
?

Nuclear physics is related to chemistry in some way but it is rightly placed under the branch of physics.

Nuclear physics is the field of physics in which atomic nuclei are studied. As in chemistry reactions are studied, nuclear physics also studies the reactions of the atomic nuclei. Hence, in this way, these two fields might co-relate but there are more differences than similarities in the field of chemistry and nuclear physics.

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.
