o The respiratory system makes it possible for
the cardiovascular system to
make blood.
The respiratory system feeds gases into the
bloodstream to support the needs
of the body.
o The respiratory system takes gases out of
the blood so that no gases circulate
in the body.
The respiratory system helps the blood make
its own gases from scratch.

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.
