Review Questions



  1. What are three ways of sub-dividing the study of ecology? Give an example of each.

  2. Name four types of research studies or methods that ecologists use.

  3. Laboratory studies are valuable for studying ecological principles in that certain factors
    can be isolated and manipulated in a laboratory setting. Give an example of how the
    effect of an abiotic factor could be evaluated in the laboratory and the response of an
    organism measured.

  4. A question that an ecologist could ask at the population level is “What factors control
    zebra populations?” Think of two examples in which another species might influence
    the zebra population.
