Deposit and Filter Feeders
a. Differentiate between deposit and suspension (or filter) feeders.
b. Provide an example of each one.
c. Are these feeders found in the water column, or on the bottom of the sea? Assume the water column starts immediately above the sea bottom.
d. What type of bottom (mud vs. sand) does each type of feeder prefer?
e. How does detritus relate to these feeders?
PART 2
a. What is the average salinity of the oceans (include units and explain the units)?
b. Where would you expect to find a higher average open ocean salinity: in the tropics (between 5 degrees N & S of equator) or in the desert belts (along 25 degrees N & S)? Why is that?
c. How does salinity compare between the Atlantic Ocean and the Pacific Ocean? Explain.
d. Is salt water denser or less dense than freshwater? Explain.
e. What do you call a rapid change in salinity with depth? What do you call a rapid change in temperature with depth? What do you call a rapid change in density with depth?
PART 3
Differentiate between squid, octopus, and cuttlefish
