Document Summary
Lecture 3 y a system is anything you make it. One of the first things to realize is that the boundaries can be very fluid depending on what your question is or what your trying to get. It can be an ant, or a classroom or the world. It really depends on the question you are going to ask but all systems have some sort of input that things happens in it and some sorts of output. Biggest ones are energy and matter, which form inputs. Gas fires up and makes the car goes and toxins are released in the air which is matter. y os in nature are normal. It is a closed system. y we are open system, we eat food, release heat, go to the bathroom. Most y ecosystem can be open or closed system. Hard to find in nature other than earth.
