Dissolved organic carbon
Water molecules itself
Phosphorus
Nitrogen
Algal biomass
Question 8
Which of the following are typically conservative major cations for lakes?
Ca2+
Na+
NO3-
K+
PO4-
Question 9
You would expect a hydrograph of stream flow to be very spiky (or show rapid changes in flow following storm events) if
the stream is draining a very small area
the stream's watershed is heavily vegetated
the stream is in an urban environment
flow in the stream is primarily determined by groundwater sources, not precipitation events
You would not expect a spiky hydrograph under any of these conditions
Question 10
Which of the following statement(s) about food guilds in streams or rivers is/are true?
Scrapers feed on relatively smaller food particles than shredders do.
Collectors compete directly with shredders for food sources.
In a freshwater system, insects are the most common consumers.
Deposit feeders are likely to be found near the surface water.
Shredders are the dominant consumers in high-order streams.
Question 11
Where in a river system would you find filter feeders in the greatest abundance?
Low-order streams
High-order streams
Near the headwaters of a stream
Intermediate-order streams
Filter feeders would be distributed evenly along the entire river system

Salt marsh
Mangrove forest
Playas
Lakes
Plateaus
A.Dissolved organic carbon
B.Water molecules itself
C.Phosphorus
D.Nitrogen
