LECTURE OBJECTIVES (Instructional goals)

AT THE END OF THIS LECTURE, YOU SHOULD BE ABLE TO:
01. Recognize the relationships that organisms have to each other in an ecosystem.
02. Understand that useful energy is lost as energy passes from one trophic level to the next (about 90% is lost).
03. Understand that useful chemicals (nutrients) are recycled.
04. Understand that humans have converted natural ecosystems to human use.
05. Understand that organisms interact in a variety of ways within ecological communities.
06. Recognize that ecological communities proceed through a series of stages to stable climax communities.
07. Name and list characteristics of the major biomes.
08. Recognize that ecological populations vary (in gene frequency, age structure, sex ratio, density).
09. Describe the characteristics of a typical population growth curve.
10. Understand why populations grow.
11. Recognize the pressures that ultimately limit population size.
12. Understand that human populations obey the same rules of growth as populations of other kinds of organisms.
13. Define selected key terms.
