Chapter 7 (180-185)

Goals: Community Ecology

  • Compare and contrast the major types of species interactions (competition, predation, symbiosis)
  • Characterize feeding relationships and energy flow, using them to construct trophic levels
  • Understand and apply the 10% Rule
  • Distinguish characteristics of a keystone species
  • Characterize the process of succession and the debate over the nature of communities
  • Perceive and predict the potential impacts of invasive species in communities
  • Explain the goals and methods of ecological restoration
  • Describe and illustrate the biomes of the world

Goals: Ecosystem Ecology

  • Describe the nature of environmental systems
  • Define ecosystems and evaluate how living and nonliving entities interact in ecosystem-level ecology
  • Outline the fundamentals of landscape ecology


  • Determine Diversity Using the Shannon Wiener Diversity Index
  • Determine Population Size using the Catch & Release Method
  • Working with Scientific Notation: Adding, Subtracting, Dividing, & Multiplying
