Define nutrients
The elements not essential for life, which allow for growth, repair, metabolism and energy release in living things.
The elements essential for life, which allow for growth, repair, metabolism and energy release in living things.
The elements essential for life, which allow growth, repair, metabolism and energy release in non-living things.
Which of the following is not a major nutrient in the ocean?
Nitrogen
Carbon
Magnesium
Sulfur
What is the biological use of magnesium?
Bone making
DNA
Making of amino acids
Making of chlorophyll
What is the biological use of phosphorus?
Bones and DNA
Coral skeleton and shells
Chlorophyll
proteins and amino acids
Which of the following is NOT a way that nutrients are replenished in the upper layers of the ocean?
run-off
upwelling
uptake
techtonic processes
What must happen to nitrogen before uptake can occur?
weathering and erosion
converted into a useable form
uptake
intake
In what ways is runoff beneficial
increase nutrients
increase growth
algae bloom
in what ways is run-off harmful?
algal blooms
increase nutrients
increase productivity
what are the three long term processes important in recycling nutrients.
greenhouse gases
algal blooms
ocean acidification
techtonic processes
decomposition
How does CO2 enter the marine ecosystem?
decomposition
upwelling
run-off
atmospheric dissolution
How does carbon get recycled in a marine ecosystem?
run-off
upwelling
decomposition by bacteria
weathering and erosion
What does Abiotic mean?
When the elements are moving through living organisms
When the Nutrients are ions in the air, water, and soil
What does biotic mean?
When the nutrients are ions in the air, water, and soil, being recycled to the environment by decomposers and bacteria
when the elements are moving through living organisms
/What are carbohydrates and lipids made of ?
carbon
hydrogen
oxygen
protein
amino acids
Why do proteins differ from carbohydrates and lipids
proteins are smaller
Proteins are made of the same elements but also nitrogen
They do not differ
proteins are most important
Sink vs. a Source
Sink- more gas moving from ocean to atmosphere
Source- more gas going into water
Sink- more gas going into water
Source- more gas moving from ocean to atmosphere
What does upwelling do?
replenish nutrients in the deep layers of the ocean
deplete nutrients from the upper layers of the ocean
replenish nutrients in the upper layers of the ocean
Which element turns into limestone during its cycle?
calcium
nitrogen
carbon
What happens during an algal bloom?
The animals love it and thrive off of it
Hypoxic and anoxic environments form
Nothing
Fish and plants grow larger
What is the biological use of Nitrogen?
making amino acids, proteins, DNA
making organic compounds
making of bones and coral skeleton
making of chlorophyll
What is the biological use of carbon
making of chlorophyll
making of amino acids, proteins, DNA
making of organic compounds
making of bones and coral skeleton
what is the planets largest carbon sink?
The ocean
Rivers
Volcanoes
Techtonic plates
What is the biological use of Calcium?
making of bones and coral skeleton
making of chlorophyll
making of amino acids, proteins, DNA
making of organic compounds
Why is harvesting bad for the marine ecosystem?
it replenishes nutrients
it depletes nutrients
Uptake vs. Intake
Uptake- when animals eat other animals and gain nutrients
Intake- when animals absorb nutrients for their own processes
Uptake- when animals absorb nutrients for their own processes.
Intake- when animals eat other animals and gain nutrients
