Which type of common mangrove has salt glands
White
Do most organisms that feed on seagrass eat it while it is alive or dead
dead
A coral has spicules. Is it stony or soft
soft
According to most scientists, during what period in the earth's history were most estuaries formed
ice age
A scientist is studying a wetland with a mangrove forest. Is this temperate or tropical
tropical
What are most common in mudflats: deposit feeders or filter feeders
deposit
What is another method that corals get their food other than extending filaments or trapping plankton
photosynthesis
If a soft-bottom shelf community is vegetated, what type of seagrass will it have?
turtle
where will you find more seaweeds: hard or soft bottomed community
hard
You are measuring tempurature and salinity in a tide pool during a low tide. What will happen to measurements
they both will increase
when a limpet seals itself against a rock to seal in moisture. What is it trying to avoid
dessication
Name 2 ways coral can asexually reproduce
budding & forming gemmules
You are looking at nonreproductive cells from two different kelps. They are the same species but have different chromosomes. How can this be
different generations
Which organisms tend to live well in all areas of an estuary
euryhaline
optimal coral growth requires warm water and what two other things
hard substrate & sunlight
polyps are connected by a thin layer of tissue
coenosarc
A sessile organism is living at a given point on the substrate of an estuary. How does the salinity that it experiences change from low tide to high tide?
The salinity will continually increase from low to high tide bringing in seawater
In an estuary a stenohaline saltwater organism can survive further inland along the right side of the river (as you float on the ocean and look back to the coast) than on the left. Is this estuary in the Northern or Southern Hemisphere?
Southern Hemisphere
identify the following organisms as benthos, nekton, or plankton: Larval fish, tuna, lobster, stingray, manta ray, jellyfish
larval fish- plankton, Tuna- nekton, lobster- benthos, stingray-benthos, manta ray- nekton, jellyfish-plankton
If you are looking for a wide variety of organisms buried in the substrate of a muddy intertidal are, should you look near the surface or deep in the mud
near the surface
Do organisms in the lower areas of intertidal zone have an easier or harder time feeding? If a Zone in the rocky intertidal zone has an amazing variety of organisms, is it most likely the upper, middle, or lower intertidal?
Easier. lower intertidal.
What are byssal threads, what organisms produce them? What type of factors determine the upper limit of living space for the intertidal organism? what about the lower limit?
strands of protein that harden to attach the organism to a substrate Mussels produce them. The upper limit of living space is determined by abiotic factors. The lower limit of living space is determined by biotic factors.
What is the commonly proposed explanation for the formation of atolls?
Atollls probably started out as fringing reefs around a volcano that was jutting above the water, as the waters rose the volcano sank the fringing reef rose to the point that it became a barrier reef witht the tip of the volcano at the center, as the waters rose or the volcano sank and eroded even more eventually the volcano was no longer above the water and the barrier reef became an atoll.
