      (1 point)
   
   

   a.		applied interdisciplinary field with an emphasis on solving problems.
   b.		well-established field that has been in existence for a long time.
   c.		theoretical discipline that will help solve the problems created by human impact.
   d.		relatively new field that will identify remedies to environmental issues.

      (1 point)
   
   

   a.		Assessing the general state of a group.
   b.		Determining the context of how data was gathered.

      (1 point)
   
   

   a.		electrical
   b.		motion
   c.		stored
   d.		heat
   e.		latent

   
   
5. What implication(s) does the law of conservation of matter have for humans?
      (1 point)
   
   

   a.		We cannot create energy because it is neither created nor destroyed.
   b.		As matter is recycled it loses some of its integrity so we need to be careful when we dispose of goods.
   c.		Natural resources are unlimited because they are used and reused by living organisms.
   d.		Disposable goods are not going “away” when we throw them out.
   e.		All of these are implications of the law of conservation of matter.

   
   
6. What implication(s) does the second law of thermodynamics have for biological systems?
      (1 point)
   
   

   a.		Systems cannot create energy because it is neither created nor destroyed.
   b.		With each transformation less available energy is available to do work so older systems have less energy.
   c.		A constant supply of energy is necessary for maintenance of biological systems.
   d.		Energy is unlimited because it is used and reused by living organisms.
   e.		None of these is an implication of the second law of thermodynamics.

   
   
7. A Titmouse and a Chickadee are living in the same territory and are using some of the same resources. The best way to classify this interaction is as

   b.		intraspecific competition.
   c.		interspecific competition.
   d.		symbiosis.

8. Which of the following is not a common strategy for successful interspecific competition?
      (1 point)
   
   

   a.		Eating prey before they are “ready” (ripe) for other species.
   b.		Spreading seeds or offspring far and fast.
   c.		Producing substances that are toxic to competitors.
   d.		The life cycle of dragonflies (the larva live in the water).
   e.		All of these are strategies for successful interspecific competition.

   
   
9. Symbiosis means

   b.		a parasitic relationship.
   c.		commensalism.
   d.		living together.
   e.		a relationship in which one species benefits and the other does not benefit.

    b.		the number of individuals in the community.
    c.		available solar energy that can be converted to biomass.
    d.		the amount of biomass produced in the community.
    e.		All of these are combined in measuring a community's productivity.
