Question 1
Nitrogen and phosphorus cycles differ in what ways? (CHECK ALLTHAT APPLY)
-Nitrogen cycle dependent on bacteria
-Nitrogen cycle has an atmospheric component
-Phosphorus cycle has no atmospheric component
-Phosphorus enters food webs mainly through primaryproducers
Question 2
In terrestrial habitats species richness is negativelycorrelated with primary productivity
True or False
Question 3
Evapotranspiration shows a positive relationship withaboveground net primary productivity This is because
A. Evapotranspiration is the amount of water that must beexchanged for CO2
B. Evapotranspiration is negatively correlated with the numberof open stomata
C. Evapotranspiration Is another way of measuring precipitationand precipitation provides the moisture plants need to grow
D.Evapotranspiration Is positively correlated with the number ofopen stomata and open stomata allow the plant to take in moreCO2
E.Evapotranspiration is the term for CO2 absorption by leavesand plants need CO2 to create the products of photosynthesis
