Plankton are unable to swim effectively and drift about at the mercyof the currents. You might think that the currents would scatterplanktonic organisms throughout the oceans, but many species arerestricted to particular regions. What mechanisms might allow a species to maintain its characteristic distribution

Many organisms living in estuaries experience freshwater and saltwater conditions each day with the rising and falling of tides. Explain how these changing conditions challenge the survival of these organisms
Describe at least one adaptation that allows a) planktonic organisms such as diatoms or jellyfish to stay in the photo zone (where light penetrates the water), and b) marine birds to thrive in the salt marsh/tidal environment.
Zones of marine organisms can usually be seen along rocky shores. How might tidal patterns result in this sort of differential growth?
Question. Benthic communities have much more diverse populations of species than open-water pelagic communities, but benthic communities are also more geographically limited in area. Why might this be so?
Biomagnification is the process by which the level of contaminants increase as they move upwards in a food chain. If bivalves in the Chesapeake Bay become contaminated from run-off, which organism will experience the highest level of contamination? a) Bivalves b) Sea duck c) Tundra swan d) Bald eagle
With respect to planktonic communities in the ocean, which ONE of the following statements is correct? a. Population numbers of plankton species vary over time, but in particular places are consistent b. Population numbers of plankton species are consistent over time, but vary from place to place c. The diversity of planktonic communities is constantly changing, and dominance by any one group is always correlated with one or more environmental factors d. The diversity of planktonic communities is stable over time, and no one group ever achieves dominance e. The diversity of planktonic communities is constantly changing, and dominance by any one group is not correlated with any environmental factor
Which marine zone would have the lowest total rate of photosynthesis? photic littoral abyssal pelagic intertidal
One of the most noticeable features of the middle tide zone along rocky coasts is a mussel bed. Describe general characteristics of mussels and include a discussion of other organisms that are associated with mussels.
What do climate change (see Concept 1.1 and Concept 3.2) and ocean acidification have in common? Design a controlled experiment to test the hypothesis that water acidification caused by acid rain would inhibit the growth of Acropora, a reef-building coral.
Recognize the differences between the pelagic and benthic divisions of the ocean.
Describe the major members of the planktonic community. Describe the eﬀ ects on the upper trophic levels of declining numbers of phytoplankton.
A) Briefly describe any two (2) examples of how the environment/habitat can limit the movements of nektonic organisms, and please include the site where you found this information B) List 5 adaptations that nektonic organisms have to move independently of currents (note: you don't have to explain these, just list them)
