Many years ago a cowboy named Juan Viborin owned a ranch in Northern Mexico. This is a very difficult area to live in because the semi desert biome makes up a large portion of this area. It is a very dry, hot, and harsh ecosystem consisting mostly of cacti and desert grasses. The types of animals in the food chain here are: the kangaroo mouse which eats desert grasses, the sidewinder snake which eats the kangaroo mouse, and the road runner bird which eats the sidewinder snake. This was a very balanced food chain; all the organisms had enough room to live and enough to eat.
Draw one graph of the following information of the animal population over a time period of 10 years.

Discuss why you think the kangaroo mouse population might be increasing.
Are the graphs of the population changes linear or exponential?
