Presentation Transcript

  1. Lesson on Biotic and Abiotic Factors

  2. What factors both living and non living will affect my life? 3 minutes To THINK PAIR SHARE

  3. Factors affecting mouse • Predators • Food • Shelter • Temperature • Weather • Competitors • Pathogens • Parasites • Clean Water

  4. Would the same factors affect this flower?

  5. Factors Affecting Plant • Predators • Food • Shelter • Temperature • Weather • Competitors • Pollinators • Soil • Nutrients • Wind • Aspect • Daylight

  6. Keywords for today • Biotic • Abiotic • Climatic • Edaphic

  7. 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

  8. Classify the factors in the picture as either biotic factors or abiotic factors

  9. List the Biotic and Abiotic Factors in the Image

  10. 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

  11. Biotic or Abiotic or Both?

  12. Decide whether these items are Abiotic, Biotic, or can be argued to be both, then place in the Venn diagram. Biotic Abiotic

  13. List the Biotic and Abiotic Factors in the Image

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

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

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

  17. Inquiry Approach • Do humans always adversely affect biodiversity? Rice fields versus Marsh Is the weather in Ireland the same? climatedata.eu

  18. 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.

  19. 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.
