Oh Deer!

Students have been investigating whether or not agricultural run-off plays a role in affecting populations of different species in the Sandy River. While students make various tables and graphs,

 we are also playing the game called "Oh Deer" to determine if there are any similarities between the two habitats. (Sandy River and Maine Woods)  There seems to be a direct correlation to the amount of food a species receives compared to its population within the habitat. More food seems to equal larger populations. Is agricultural run-off food?
