What are nutrients?
The elements essential for life, which allow for growth, repair, metabolism and energy release in living things
When the elements are moving living organisms
When the nutrients are ions in the air, water, and soil, being recycled to the environment by decomposers and bacteria
Things in food that give to vitamins
Name the Nutrients found in the Ocean
Hydrogen and Oxygen
Nitrogen, Carbon, Magnesium, Calcium, Phosphorus
Carbohydrates, Lipids, Proteins,
Carbon, Hydrogen, Oxygen, Nitrogen
When the elements are moving through living organisms
Biotic
Abiotic
When the nutrients are ions in the air, water, and soil, being recycled to the environment by decomposers and bacteria
Biotic
Abiotic
What causes upwelling
offshore winds pushing the water back
Mid-ocean ridges
A and C
None of the above
Draw what happens during upwelling
(a) when organisms use nutrients for their own processes.
Explain the Carbon Cycle.
What is the first step of the Nitrogen Cycle
Then uptake of Nitrates (usable form of nitrogen) by
phytoplankton and other producers and passed up the food
chain (intake)
Nitrogen(N2) is fixed from the atmosphere by Cyanobacteria and converted into Ammonia (NH4+)
Ammonia then gets converted into Nitrites (NO2) and then
into Nitrates** (NO3) by other types of bacteria
sinking
of detritus (dead rotting animals) - decomposition of detritus
into recycled nutrients - upwelling from deep sea back to atmosphere
______ _______ is when CO2 enters the water, forms carbonic acid then breaks down into hydrogen bicarbonate and hydrogen ions
(a)
Explain the process of eutrophication
Use of calcium
Needed to make bones and DNA
Making of organic compounds
Plants need it to make chlorophyll, critical for photosynthesis
Needed to make bones, coral skeletons and shells
Uses of Nitrogen
Making of amino acids and proteins
To make proteins and DNA
Makes amino acids, proteins and DNA
None of the above
What are carbohydrates made of
Carbon
Hydrogen
Oxygen
Nitrogen
All the above
Lipids form polymers called (a)
Lipids form polymers which are made of
Amino acids
1 glycerol and 3 fatty acids
3 glycerols and 1 fatty acid
2 glycerols and 4 fatty acids
Draw the formation of a lipid
What are some ways nutrients enter and are replenished at the surface
Atmospheric dissolution
Run-off
Excretion and decomposition
Upwelling
Proteins contain
Carbon, hydrogen, oxygen, and nitrogen
Carbon and hydrogen
Sodium bicarbonate
Carbon, hydrogen, and oxygen
Cellulose is a
Monomer
Polymer
Drawing the structure of a Carbohydrate
Photosynthesis takes place only at the surface due to limitations of light and this part is called the
(a)
Describe the process of Upwelling
Describe the steps in the Phosphorus cycle
How does harvesting deplete nutrients from the sea
Humans take organisms out from the sea taking out the nutrients with them
Trick question- harvesting doesn't delete nutrients form the sea
Boating companies take nutrients up with their boats
By causing run-off increasing the fresh water and decreasing the amount of nutrients
