a. What are the different trophic categories/levels in a food chain/web? How do you expect bioavailable contaminants to move in a food chain?
Feed level defined by primary source of energy (green plants first) top quaternary consumer -> tertiary consumer -> secondary consumer -> primary consumer -> primary producer bottom
b. What are the main differences between terrestrial, aquatic, and detrital food webs/pyramids?
-
c. Why are terrestrial trophic levels not as efficient as those found in aquatic systems? How many trophic levels do most ecosystems support?
-
e. What is ecological succession and what are the types? What role does fire/other disturbances play in succession?
• Succession: transition of one biotic community to another
Fire and Succession • Some pine species require fire • Resilience: ability of ecosystems to return to normal after disturbance • Tipping Point: situation in human impacted ecosystem where small action catalyzes major change in system state
f. What are biomes? Be able to identify different biomes and what factors control where they occur. Which biomes are the most productive and why?
-
h. What do we call small regions in the environment where the climate differs from the overall climate?
