At the end of today’s lesson you will be able to
• Define biotic, abiotic, climatic and edaphic• Give examples of each type of factor

Abiotic Factors
• Climatic and Edaphic
• Climatic - factors that relate to the weather• Edaphic – factors that relate to the soil

What climatic factors could we measure?
• Light Intensity• Humidity• Wind speed• Temperature• Aspect• Slope

What edaphic factors could we measure?
• Soil pH• Amount of water in soil• Soil Temperature• Soil Air• Soil Texture

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.

Questions on Deer Population
• During which 10 year period did the greatest increase in the deer population occur?
• 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.
