Oxygen
This process stores energy and adds Oxygen to the atmosphere.
What is Photosynthesis?
The liquid form of stored carbon.
What is oil?
Fresh water stored over long periods of time in solid form.
What are glaciers?
Plants and Animals cannot use this from the atmosphere.
What is N2?
Where phosphorous is stored, or where the phosphorous cycle begins.
What are rocks/geosphere?
This biological process removes O2 from the atmosphere.
What is breathing?
An early form of coal.
What is peat?
The process that moves H2O from the hydrosphere into the atmosphere.
What is evaporation?
This simple life form is important in converting N2 into NH4.
What are Bacteria
The process that removes Phosphorous from exposed rocks and brings it into the hydrosphere.
What is weathering?
Oxygen (O2) is converted into this molecule when it is used in our cells to make energy.
What is CO2?
A common gas that contains carbon.
What is CO2?
Water is a molecule made up of these two elements.
What is oxygen and hydrogen?
A molecule converted by bacteria from nitrogen gas into a form that plants can absorb.
What is Ammonia?
The name for the P04 which can be used by plants.
What is phosphate
A process that removes oxygen from the atmosphere and converts it into CO2 and H2O vapours.
What is burning/combustion?
A geological process that releases carbon dioxide into the atmosphere.
What is a volcanic eruption?
During this biological process water is a product?
What is breathing?
The name of the molecule with nitrogen that many plants can use? (NO3, NO4)
What are Nitrates?
Land that is sometimes responsible for excess phosphorous levels in rivers.
What is agricultural land/farms?
What element can lead to low O2 levels in the Hydrosphere?
What is phosphorous?
A process that allows carbon to return to the geosphere when an animal or plant dies.
What is decomposition.
When water moves through a plant, from its roots to its leaves.
What is transpiration.
An environment where can bacteria take NO3 and convert it into N2 again has to be low in _________.
What is O2/oxygen?
Excess phosphorous can cause plants and algae to bloom, which can reduce the level of this in rivers and lakes.
