Download Final Exam Review – Exams 3 and 4

Welcome
• Please sign in at the front..
• Please be aware that you will be put into a
team: 1, 2, 3, or 4, so please go ahead and
break yourselves up into these teams so that
we can get started quickly. If anyone comes in
late, please take them into your teams. Don’t
just leave them hanging.
Getting started
• This review will be posted on my SI resources site (See
Vista), so there’s no need to write everything down.
(unless you just want to)
• This session is much different than a regular SI session:
this is a fast-paced review rather than going into the
material in depth.
• Shameless plug: People who come to my SI sessions
typically do better on their tests. Please come, having
more people generally makes the sessions more
enjoyable.
Rules
• Each team will have a chance to work together to answer questions
in order: Team 1, 2, 3, 4
• If the team cannot answer all parts of a question, the question will
be passed to the next team (this is separate from the bonuses).
• Please put your notes away unless you are writing in them, no
points will be awarded for finding info in your notes.

Phosphorous and Nitrogen are considered
limiting factors in organism growth. What
does this mean?
the availability of phosphorus and nitrogen govern the
rate of growth of many organisms.
In ecosystems an excess of phosphorus can be
problematic, especially in aquatic systems, causing
eutrophication and algal blooms.

What is the missing sink, and why is it
important?
Not all carbon sinks have been accounted for (i.e. there is
not as much carbon in the atmosphere as would be
expected by adding up the amount absorbed by all the
known sinks), so it is assumed that there is some carbon
sink that we do not know about, and we must find out
what it is, and be careful not to disrupt it. Otherwise, that
carbon would go into the atmosphere, causing further
warming.

Briefly describe the process of Nitrogen
fixation, nitrification, and denitrification
-Nitrogen from the atmosphere is fixed so that it can be
used by plants. The three ways it can be fixed are

legumes
2. Lighting
3. Artificial processes (by humans)
-Nitrogen can be further nitrified by bacteria
