Q: Where do you NOT find mangroves on this planet?
Answer:
and why not? Europe - too cold Which of the following is NOT an ideal nursery
habitat? Open Ocean Red tides along the Gulf Coast are caused by dinoflagellates
that create toxins called brevetoxins. True Plankton blooms along coastlines occur
due to increased nutrients? True Blue carbon habitats are important specifically
because of their ability to remove carbon from the atmosphere or the water column
and transport it to the seafloor when they die Mangroves provide an important habitat
for fish, crustaceans, sponges, bivalves, etc. All of the organisms that live attached to
the roots are referred to as: epiphytes Which of the following is NOT a condition
needed for these young mangroves to grow? cold water If a large pod of orca whales
moved into an area and began to hunt the local sea otter population, what would you
expect to happen to the density of the kelp forest? decrease Which of the following is
not part of the niche (job or role) of phytoplankton in the open ocean? decomposition
of dying organisms In this diagram of the carbon cycle, what does the B line
represent? photosynthesis The ocean's biological pump results in most carbon in the
ocean being sent to this location for long term storage: seafloor
, Q: Which line represents movement of carbon up the food chain?
Answer:
D Where can calcium carbonate be found in the ocean? in coral skeletons ______
delivers nutrients to the deep sea, and ____________ delivers some back to the
surface waters. Marine snow, upwelling Which of the following process does NOT
replenish nutrients to surface waters? harvesting Which of the following does NOT
deplete nutrients from surface water? volcanic ash What nutrients are needed by
organisms to make DNA? nitrogen and phosphorous Which nutrients get passed up
the food chain? all of the above A cnidarian that builds a hard calcium carbonate
skeleton around itself? coral polyp Which of the following is NOT a characteristic of
the phylum Cnidaria? tube feet for feeding Which of the following events is most
likely to trigger a mass spawning event on a coral reef? A particular moon phase
Which life cycle has a life cycle that includes both spawning --> larvae --> a benthic
polyp that forms a colony --> budding --> juvenile --> adult? jellyfish What is the
function of nematocysts? to inject venom
Q: Meiofauna are tiny invertebrates that live in spaces between sediment. TRUE
Phylum Porifera are known mostly as sponges Definition: A habitat in which the
fresh water of a river meets the salt water of the ocean. estuary Definition:
mixture of fresh and salt water brackish water Definition: A species whose
numbers are so small that the species is at risk of extinction endangered species
Definition: a place where an organism makes its home habitat The Everglades
have been completely restored. False Is this the best type of graph to be used for
the data given?
Answer:
Yes, this is correct. The Epipelagic Zone is known as the Midnight Zone False The
majority of the seafloor is in the... Abyssalpelagic Zone These depths are only found
within trenches Hadalpelagic Zone Photic zone goes down 200 feet
