22. The Deer Population
A field study was conducted to observe a deer population in a given region over time.
The deer were counted at different intervals over a period of 40 years. During this period of time both ranching and hunting increased in the study region.
A summary of the data is presented in the table.

23. Questions on Deer Population

State one possible action that could have been used to help maintain a more stable population of deer in the area.
Identify an abiotic limiting factor for the deer populations.
Identify a biotic limiting factor for the deer populations.
List two problems an overpopulation of deer can cause in the environment.
