Gen Bio Unit 2: Interdependence of Organisms

Theme 2: Interaction with the Environment

Unit 2: Interdependence of Organisms (Question-based Objectives)

Keywords: biotic factors, abiotic factors, population, exponential growth, carrying capacity, logistic growth, limiting factors, immigration, emigration, birth, death, competition, predator adaptations, prey adaptations, symbiosis, mutualism, parasitism, commensalism, food chains, food web

Objectives:

  1. What factors cause population changes?
  2. How has human population changed in the past 350 years?
  3. What determines the types of plants and animals in a region?
  4. What are some ways that different species interact with each other?
  5. How are human activities affecting our planet?

Activities/Labs:

  1. 50 Late Summer Observations- focus on ways organisms interact with their environment
  2. Grasshopper Mark-Recapture Lab Worksheet
  3. Deer Population Graphing Activity
  4. Human Population Growth Graphing Activity
  5. Ecosystem Evaluation Activity
  6. Symbiosis Worksheet
  7. Human Impact on the Biosphere Project–  (power production, livestock operations, pesticides, herbicides, fertilizers, landfills, irrigation, suburbanization, commercial fishing, CO2 level changes over time, etc.) Must use Research Information Sheet as a Works Cited page.

Extensions:

  1. Monarch Watch
  2. Global Warming

Further Research: population density, population dispersion, survivorship curves (K and r selection), infant mortality, ecological footprint, keystone species, ecological succession

  1. I know this site provides quality depending content and extra
    data, is there any other web site which gives such
    things in quality?

    • I know a number of folks that contribute here make their materials available on their own websites. All my labs and other documents are over on biologyrocks.org. Who else shares things that could help our friend from California
