Chapter 36 & 37 POGIL Review Population Growth Population Distribution Ecological Relationships Energy Transfer in Living organisms Ecological Pyramids Nutrient Cycles Global Climate Change Eutrophication

Population Growth What causes an increase in population? What causes a decrease in population? What is a survivorship curve? What is the difference between Type I, II, and III? What is the difference between exponential growth and logistical growth?

Population Distribution Density vs. Distribution (dispersion) Why different distributions (dispersion)? Density dependent vs. density independent factors

Ecological relationships Examples of relationships within an ecosystem Inter-specific vs. Intra-specific competition

Energy Transfer in Living Organisms How does the law of conservation of energy apply to living organisms? What is the food eaten by an organism used for?

Ecological Pyramids Why can’t there be 10 levels within an energy pyramid? What is a “trophic” level? What is the approximate amount of energy available for transfer from one trophic level to the next? What does a pyramid of numbers show? What is biomass? How is it measured? What organism is NOT included in the pyramids? What organism is ALWAYS at the base of any pyramid?

Nutrient Cycles What processes are involved in the water cycle? What processes are involved in the carbon cycle? What processes are involved in the nitrogen cycle? Why is it important that these nutrients be recycled?

Global Climate Change What is albedo? How has melting ice caps effected albedo? How has the above contributed to global warming? Data shows the temperature of the earth is increasing. Why do scientists think this is happening? How does global warming effect oceans?

Eutrophication Increased nutrients in a lake, causing a dense growth of plant life and death of animal life from lack of oxygen.
