Indian Mounds and Fall Line CIties

Macon, GA is located along a geographical feature known as the fall line. The fall line is the area where the upland region of the Piedmont meets the Atlantic Coastal Plain. Sites along the rivers on these fall lines have long been sought after by civilizations because they usually have rapids and waterfalls. These features can mark the head of navigation and are a good source of water power. The early settlers came to Macon because of its location on the river. The river supplied them with water and food. The later settlers were attracted to the area because of the trade that the river allowed.

Negative Feedback Loop

A negative feedback loop is a feedback loop in which a system responds to s change by returning to its original state, or by decreasing the rate at which the change is occurring.

An example of a negative feedback loop can be seen through the levels of sugar in the blood stream after eating a candy bar. The graph below shows how Dr. Rood's blood sugar reacted to a candy bar. You can see the response and return to homeostasis over a period of time.
