Elicit, outline, and discuss the factors which are primary in determining population growth. Arrive at a mathematical formula which solves for population.
Review the Malthus theory of population growth and food availability. View and analyze two graphs which present population and food deficit graphs and population and food sufficient graphs. Determine factors which will contribute to the ability of humans to not surpass the carrying capacity and create a food deficit. Introduce demography as the study of human population trends. List birth rate, death rate, fertility rate, life expectancy and migration as factors.
Discuss Malthus theory of population growth and food deficit. Analyze graphs showing the actual growth of population and food supply compared to the Malthusian theory graph. Discuss factors which allow the food supply graph to "j" curve like the population curve. Analyze assumptions made based on technology. Elicit a formula to determine the population growth based on births, deaths, immigration and emmigraion. Define and explain demography
Define and discus predation and parasitoids. Discuss the behavioral, morphological, and chemical defense organisms have developed to counter predators. Introduce parasitism, mutualism, and commensalism. Discuss the part each effect has on the ecology of the community, particularly as it relates to resource partitioning.

Define the term keynote species as a metaphor from architecture.
Explain how a keystone specie is a low abundant specie which has a large effect on a community. Discuss the role of keystone predators and the effect each has on producers in the community and other primary and secondary consumers.

introduce resource partitioning. Discuss fig 20.2 found in the textbook, analyze how the graphs indicate the overlapping competition for food by different species, with one of them becoming extinct. Discuss the 3 types of resource partitioning
Outline and discuss resource partitioning. Indicate how some individuals of competitive species will compete for overlapping resources. List and discuss the various types of resource partitioning; temporal, spatial, and morphological. Discuss predation, define and include examples. Introduce parasitoids and display examples...Discuss how predators play an important role in controlling the abundance of prey. Discuss behavioral, morphological, and chemical methods used by prey. Introduce parasitism and herbivory.
Elicit a definition for community and that community ecology relates to the study of the interactions among species. Define symbiotic relationships. Introduce competition as the struggle of individuals to obtain shared limiting resources. List limiting resources and discuss which are density dependent.
Introduce the competetive exclusion principle, define and use examples,
Elicit all relevant definitions of community, symbiosis, competition, limiting resourse.
Discuss how competition involves the struggle of individuals to obtain a shared limiting resource.
Introduce the competitive exclusion principle along with the possibility of extinction due to inability to coexist.
Discuss survival of fhe fittest and the possession of a superior competitive ability.
Define and discuss the study of demography. Elicit the factors which influence population size; include birth rate, death rate, fertility rate, life expectancy, and immigration. Analyze why the birth rate by definition is misleading. Introduce the formula for determining the crude birth rate and the global population growth rate. Use a few examples to determine both.
Define demography as a study. List and discuss the factors which influence population gross size. Include definitions and discussions on birth rate, death rate, fertility rate , life expectancy, and migration effects. Analyze that size is influenced by immigration, emigration, birth rate and death rate. Discuss the problems with using birth rate as a determinant.
Introduce the crude birth rate, the global population rate formula and the formula used to determine the population doubling time.
