Factors affecting mouse • Predators • Food • Shelter • Temperature • Weather • Competitors • Pathogens • Parasites • Clean Water
Factors Affecting Plant • Predators • Food • Shelter • Temperature • Weather • Competitors • Pollinators • Soil • Nutrients • Wind • Aspect • Daylight
Keywords for today • Biotic • Abiotic • Climatic • Edaphic
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
Classify the factors in the picture as either biotic factors or abiotic factors
Decide if Factor is Biotic or Abiotic Write B if Biotic _______ Corpse _______ Snail _______ Vegetation _______ Bread Mould _______ Trees _______ Soil _______ Plastic _______ Pipe _______ Air _______ Wind Write A if Abiotic _______ Mouse _______ Rocks _______ Water _______ Fish _______ Paper _______ Glass _______ Aluminum _______ Wooden Ruler _______ Sand _______ Clouds
Decide whether these items are Abiotic, Biotic, or can be argued to be both, then place in the Venn diagram. Biotic Abiotic
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.
