300 What is an ecosystem and what are its components?
300 Relate the pyramid configuration to energy flow and biomass flow?
300 What is the distinction between a food chain and  a food web and why is the food web the component of a sustainable ecosystem?
400 1. The role of autotrophs and heterotrophs (herbivores, carnivores, omnivores, decomposers) in an ecosystem
400 2. Food chains/webs and pyramids to demonstrate the flow of energy through an ecosystem
400 3. Define population and species
400 4. Growth rate: growth without limits, growth with limits, boom and bust, and zero population growth
400 5. Population density: density-dependent limiting factors (competition, predation, parasitism, stress) vs. density-independent limiting factors (weather, human activities)
400 6. Human population growth
500 Students in Biology will develop the abilty to:
500 1. Analyze a food chain/web and pyramid, including the relationships of the autotrophs and heterotrophs and flow of energy,
500 2. Compare and contrast the relationships between different populations in an ecosystem,
500 3. Determine the density-dependent and/or density-independent factor affecting a population,
500 4. Describe the history of human population and discuss what may happen to the human population in the future.
600 1. Produce a food chain/web and food pyramid
600 2. Analyze a food pyramid
