42. What is a lichen? What role does each of the organisms that make up a lichen play?
43. What role does fungi play in the carbon, nitrogen and phosphorus cycles?
3. Fungi are heterotrophic organisms. What does this mean? 4. What role do fungi have as decomposers in nature? 5. Plants: What is the function of vascular tissue? 6. Plants: Give one adaptation seen in plants that allowed them to invade "dry" land?
Question 1
Nitrogen and phosphorus cycles differ in what ways? (CHECK ALL
THAT APPLY)
-Nitrogen cycle dependent on bacteria
-Nitrogen cycle has an atmospheric component
-Phosphorus cycle has no atmospheric component
-Phosphorus enters food webs mainly through primary
producers
Question 2
In terrestrial habitats species richness is negatively
correlated with primary productivity
True or False
Question 3
Evapotranspiration shows a positive relationship with
aboveground net primary productivity This is because
A. Evapotranspiration is the amount of water that must be...
carbon, hydrogen, oxygen and nitrogen make up the bulk of the
atoms in the human body. However, there are many trace elements
present as well. Pick three of these trace elements and do a little
Internet research to find out where they're found and what they're
used for in the body.
What does it mean to use an open collector? What role does the "pull-up" resistor play? Say device "A" wanted to send a "1" on the wire, what would device A need to drive? What would the other devices be driving when they weren't trying to use the bus? Say device "A" wanted to send a "0" on the wire. What would device A need to drive? What would the other devices be driving when they weren't trying to use the bus?...
