6. As altitude increases, air pressure
(1) decreases
(2) increases
(3) remains the same

1) decreases

the air presure decreases because there are less particals the higher up you go

i was thinking 4.0 v hope this

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.
