An increase in the external supply of nutrients to an ecosystem that results in an increase in plant growth
Effect of increasing the concentration of a limiting nutrient on phytoplankton growth rate
Why would eutrophication be called too much of a good thing?
What are 4 elements that tend to limit plant growth?
Do plants take up organic, or inorganic substances?(understand difference of two
terms) What molecule do they take up to get phosphorous (P)?
Why does the growth curve (growth rate vs nutrient concentration) curve over?
What is this curving over called?
Why do we need to determine which nutrient is limiting to control eutrophication?
What is Liebig’s law?
How does it apply to plant growth? What is it’s relationship to eutrophication? (That is, why was it discussed in this
Where does the C, N, and P come from (externally) in lakes?
What is the figure of chlorophyll vs total P of field observations of lake surveys telling us?
How would you test whether a nutrient is limited using a laboratory experiment?
Which element was it surprising to find was limiting in lake water using laboratory
experiments? How did the laboratory experiment not represent what is actually happening in lakes?
What was the controversy concerning nutrient limitation?
What did the field experiments indicate about nutrient limitation in lakes? (that is,
understand the results of these experiment relative to the laboratory experiments).
"StudyBlue is great for studying. I love the study guides, flashcards and quizzes. So extremely helpful for all of my classes!"Alice , Arizona State University
"I'm a student using StudyBlue, and I can 100% say that it helps me so much. Study materials for almost every subject in school are available in StudyBlue. It is so helpful for my education!"Tim , University of Florida
"StudyBlue provides way more features than other studying apps, and thus allows me to learn very quickly! I actually feel much more comfortable taking my exams after I study with this app. It's amazing!"Jennifer , Rutgers University
"I love flashcards but carrying around physical flashcards is cumbersome and simply outdated. StudyBlue is exactly what I was looking for!"Justin , LSU
