Ecology

Some higher order thinking questions.
Page 1008
  1. How does an ecosystem differ from a community? (Page 1009 and lecture)
 (Fill out your answers here.)
  1. WHY does Ecological succession end with a Climax Community like McMillian Park?
  1. WHY does neither a food pyramid nor Evolution break the 2nd Law of Thermodynamics? (indicates that after many more reactions, much energy is "LOST" and more disorder, overall, sets in). See poster and Lecture P1022.
  1. P 1033
    1. How is the movement of energy through a food web differ from the movements of nutrients?
    2. Also (part B) Explain why
  1. WHY is the Nitrogen Cycle so important to your life, despite the fact that the is approximately 78% Nitrogen?
  1. HOW does the study of Microbiology help us understand the Nitrogen cycle?
  1. If the Ozone is such a problem near the surface of the earth, WHY is the Ozone layer above DECREASING?

Followup to interactive Lectures (9)

Biology 11 - June 8, 2000
Print neatly and Small - use point form.
    1. Explain 3 factors that limit population growth and HOW they do it.
    2. What is the difference between density dependant and density independant factors?
  1. Describe a Pyramid of energy in terms of energy flow and 2nd Law of thermodynamics.
  1. Explain HOW photosynthesis related to respirtation in the Carbon Cycle in Ecology.
    Hint: see Lecture on 2 organelles (M + Ch)
    Also: WHY is photosynthesis so important?
  1. Be sure to have the population formula mastered and that you can do problems.
