Transcript Carbon and Nitrogen Cycle - Alamance



 In
oceans
 Air
 Soil
 And ALL LIVING
THINGS:organic
 Sugar, Coal and Diamond
is the gas that
adds the sun going
through
photosynthesis.
 The CO2 is pulled
from the air and
converted to C for
plant food.
 CO2

in the Food
chain the
Carbon is
moved from
animals that
eat plants
(herbivores)
and animals
that
consume
them
(carnivores).
 When
plants and
animals
dies their
bodies
wood and
decay
bringing CCarbon in
the ground.

EXHALE
Breathe in Oxygen
Exhale Carbon Dioxide
This process is called
RESPIRATION
 Human
burn fossil fuels
to Heat.
 This heat enters the
atmosphere as carbon
dioxide
 EACH YEAR ½ million
tons (100 million
elephants) of C is
released to atmosphere
by fossil fuels then to
our seawater

The oceans and other bodies of water soak up C02


Carbon is a greenhouse gas, which keeps the earth warm.
Too much C causes the earth to become too hot and the planet
becoming warmer.


 Nitrogen-fixation
Atmospheric: Nitrogen
(N2) is oxidized at high
temperatures (by
lightning, in internal
combustion engines) to
make nitrite (NO2) (which
is deposited throughout
the atomsphere)


Conversion to Ammonia. As amino acids and nucleic acids
require N in the form of Ammonia, if nitrate (NO3) present,
it must be converted to NH3.

Step 3: Biological Use. Ammonia is incorporated into
proteins, nucleic acids

Step 4: When organism dies, ammonia is released back
into the biosphere through the process of Ammonification,
in which water is added to proteins to make carbon dioxide
and ammonia.

Step 5: If ammonia released into oxygen rich (anerobic) soil,
other bacteria can convert it into nitrite or nitrate through the
process of Nitrification: NH4+ + 2O2 = NO3- + H2O + 2H.

atmospheric N2 through the process of Denitrification. In
this process, bacteria use nitrate as an Oxygen source for
respiration: C6H12O6 + 4NO3- = 6CO2 + 6H2O +
