Biomes/ALZs
We will use this page for good resource links and test question suggestions. PLEASE keep in mind that the test is 75% from the book, and 15% from projects. So, don’t write obscure questions classmates who did not do your research won’t know. Maybe reread what is the book first? Help each other understand unique (but not obscure) climate features, dominant vegetation, and representative animals that occur there for biomes and unique zonation, productivity, and relative salinity for ALZs (fresh, brackish, salt).

Which zone makes up most of the net primary productivity for intertidal zones?
What is the major factor that has led to the differences in biomes? (Precipitation)
Why do plants in dryer biomes tend to be smaller? (Use less energy and conserve water)
Why do biomes near the poles have a nickname of cold deserts?
Why do some biomes have two seasons while others have four?

1. What is the composition of the troposphere? (N2, O2, Variable Gases – water vapor, CO2, Methane, N2O, O3)
2. In a prairie, what normally prevents trees from growing? (drought and fire)
1. The taiga or the boreal forest consists primarily of which type of trees?
2. What is one major problem facing the taiga?
Dylan, I told you guys we won’t test on human impacts. Try another?
1. Why are chaparrals prone to forest fires?
2. Why are trees in the chaparral biome dwarfed?

Links that might be helpful to review?

I completely spaced and missed this assignment ’till now.
for inland wetlands (aka, swamps):
1. why are swamps such fertile lands? (two primary reasons)
2. how do swamps differ geographically from salt marshes?, in other words, where are they NOT found and why? what is the primary difference in the two ALZ’s?
Jason, you gonna give folks the answers?
1. Why do winds in the northern hemisphere curve to the right?
2. Name three plant adaptations to limited precipitation.
Priya…look carefully at the diagram. Not all gobal winds in the northern hemisphere go to the right. That’s a misconception. They go right around the equator at least. Each band of convection cells goes a different direction-very complex. Regardless, the Coriolis Effect gives our global winds some direction…
