Where is the sternum located? in the skull in the thoracic cage in the vertebral column in the trunk

Thoracic Cage

Explanation:

This ensemble of bones is also known as the "breastbone" and is located in the central part of the chest (Thoracic Cage). It helps to protect the heart, lungs and major blood vessels.

It's formed by the manubrium, body and the metasternum.

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.
