Total questions: 20
Worksheet time: 15mins
Why is this process important for coastal systems?
It brings up nutrients from the depths
It brings up phytoplankton from the depths
It brings up benthic organisms for seabirds to consume
It brings up sediment from the depths
Where in the ocean do you find the most oxygen and why?
At the bottom; cellular respiration by marine organisms
At the surface; cellular respiration by marine organims
At the bottom; cellular respiration by phytoplankton
At the surface; photosynthesis by phytoplankton
How can you know a nutrient is "limiting?"
Add it to the environment. If there is more biomass (more organisms or growth) after adding it, it is limiting.
Add it to the environment. If there is less biomass (less organisms or growth) after adding it, it is limiting.
Add it to the environment. If there is no change in biomass (less organisms or growth) after adding it, it is limiting.
Which term describes the transferring of a chemical from one trophic level to the next, with the highest chemical concentrations at the highest trophic level?
chemoaccumulation
chemomagnification
bioaccumulation
biomagnification
Check all the necessary conditions you for natural selection to occur.
Variation in traits
Traits heritable
Some individuals reproduce more than others
Millions of years
Reproduction
The Biological Species Concept says that
If two individuals look the same, they are the same species
If two individuals look the same and live in the same area, they are the same species
If two individuals come from the same ancestor, they are the same species
If two individuals can interbreed and have viable, fertile, offspring, they are the same species
Why is solar energy (yellow) being reflected back to the Earth?
Earth's magnetic force keeps it from going back to space
It is too weak to escape Earth's atmosphere
Greenhouse gases already in the atmosphere absorb the solar energy that leaves the Earth, then re-emit it back to Earth
Greenhouse gases store solar energy from the moment they leave the troposphere. They release it once they're higher in the atmosphere.
How is climate change affecting ocean ecosystems? Choose all that apply.
Increased ocean temperatures are resulting in a loss of habitat for reef fish
Increased CO2 levels in the ocean are preventing calcium carbonate-shell production of organisms at low trophic levels, like pteropods
Increased acidification is disintegrating the skin of top predators, like sharks
Increased ocean temperatures are causing coral bleaching
Which contribute to the occurrence of a dead zone? Choose all that apply.
Nutrient run-off from land into a body of water
Overgrowth of algae
Cellular respiration by bacteria
Eutrophication
What color is most rapidly absorbed in the ocean?
blue
yellow
red
green
What nutrients limit phytoplankton growth in the ocean? Check all that apply.
nitrogen

Which of these was NOT evidence for the theory of continental drift?
rake-like marks at the bottom of the ocean from when the continents moved
matching coastlines of different continents
plate tectonics
mid ocean ridges
fossils of the same species in different continents
What potentially limits photosynthesis? choose all that apply.
sunlight
nutrients
temperature

Which of these describes a planktonic organism that remains planktonic its entire life?
nekton
plankton
meroplankton
holoplankton
What causes a red tide and why are they important?
coccolithophore blooms; they are an important source of nutrients
diatom blooms; they are very toxic
dinoflagellate blooms; they are very toxic
radiolarian blooms; they are an important source of nutrients
Which cetacean group is capable of echolocation?
odontocetes
mysticetes
Which is not a problem caused by fisheries?
Overfishing
Bycatch
Coral bleaching caused by the aquarium trade
Introducing invasives as live bait
Ghost fishing
Which of these reproduction strategies describe laying a fertilized egg, without birth to live young?
viviparous
ovoviviparous
oviparous
Mark all that is true based on this diagram
Wave 1 and Wave 2 have equal frequency
Wave 1 and Wave 2 have equal wave height
this is showing constructive wave interference
this is showing destructive wave interference
A wave that is in water of 20 meters depth has a wave base that is 30 meters deep. What can you conclude about this wave based on this information?
this is a shallow water wave
this is a deep water wave
this is a tsunami
this is a seiche
