is the sixth element on the periodic table. Carbon as a solid can
be found nearly everywhere. In a gaseous state, it primarily is found
in carbon monoxide (CO) or carbon dioxide (CO2). Since CO2 can be
dissolved in water, the liquid state of carbon dioxide is not really liquid
is what is responsible for trapping light energy for photosynthesis.

of the particles with no barriers present.
is one billion tons.
Effect—A warming effect on the Earth. Certain gases in
the atmosphere absorb long wave radiation being emitted from the Earth
and then reemit heat in all directions, including back down to Earth.
Only a small amount of thermal energy comes back to the surface, but this
warms the Earth. It is only a slight increase in thermal energy,
but an increase of only a few degrees in average surface temperature could
have disastrous consequences.
gas—Any gas that contributes to the Greenhouse Effect. e.g.
CO2, N2O, CH4
compounds contain only carbon and hydrogen. They combust easily and
can therefore be a good source of energy.
is the area of the ocean that receives light from the sun. It is
about 200 meters deep.
is the process where plants make food. It is a metabolic process
that utilizes solar energy to convert CO2 and H2O into a certain type of
sugar called glucose (C6H12O6). This sugar is used for food.
6 CO2 + 6 H2O+ solar energy --> C6H12O6 + 6 O2.
ocean dwelling organisms are very small. They get food by photosynthesis
and are food for zooplankton and other larger organisms.
this is just the opposite of Photosynthesis. Glucose is burned in
the presence of Oxygen producing useful energy. Water and carbon
dioxide are two byproducts.
C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O+ useful energy.
act of separating something and dealing with it alone. e.g. Filtering
carbon dioxide out of the air and storing it elsewhere.
heat warms the upper layers of the ocean creating a sharp temperature difference
with depth in the ocean. This temperature difference allows for only
the top layer, about 200m thick, to continually be mixed by wind.

tiny organisms eat phytoplankton and microzooplankton. They are far
less numerous than the two others mentioned.
