The 4 Cycles of Life
- The Carbon
Cycle
- Natural process
of circulation of
Carbon between
the atmosphere
and all living
things.
- Forms 0.04% of
the Earth's
atmosphere
- Green Plants use
Carbon Dioxide to
make sugars and
Oxygen
- The Carbon Cycle is the
key mechanism by
which energy from the
sun is converted into
chemical energy.
- Decomposers
release Carbon
Dioxide when
decomposing
dead
organisms.
- Natural process
of circulation of
Carbon between
the atmosphere
and all living
things.
- The Phosphorous Cycle
- Circulation of
Phosphorous from rocks
to living organisms and
back again.
- Phosphorous is a very
reactive element,
usually found in rocks.
- The Phosphorous
Cycle is way slower
than all of the other
cycles,
- Phosphate
compounds in rocks
are released as the
rocks weather.
- Weathering is the breakdown of
rocks by physical means and
chemical means.
- Weathering is the breakdown of
rocks by physical means and
chemical means.
- The Phosphate
dissolve in water and
are taken up by plants
for nutrients.
- When living organisms die, their
phosphates are deposited back into
the soil. Over very long periods, the
soil forms rock and waits till erosion
for the phosphate to get released.

- The
Water
Cycle
- The 3 main processes
in Water Cycle are-
Evaporation of Water,
Condensation of
Water vapour and
finally precipitation.
- Water exists in
three states -
Solid (ice), Liquid
and Gas(Water
Vapour).
- Water exists in
three states -
Solid (ice), Liquid
and Gas(Water
Vapour).
- The Water
Cycle is driven
by energy
from the Sun.
- Ice is less dense
than water,
which means
that it floats on
water.
- Ice is less dense
than water,
which means
that it floats on
water.
- Without the
insulating layer
offered by the ice
surface, more and
more of the ocean
would freeze.
- The 3 main processes
in Water Cycle are-
Evaporation of Water,
Condensation of
Water vapour and
finally precipitation.
- The Nitrogen
Cycle
- Most common
gas in the air
- Fixation is the
process that makes
Nitrogen available
to all living
Organisms.
- Fixation is the
process that makes
Nitrogen available
to all living
Organisms.
- Forms about
78% of the
atmosphere
- Forms about
3% of the
human body
- When Organisms die, the
remains are broken down
by decomposers, which
release Nitrogen back to
the atmosphere
- When Organisms die, the
remains are broken down
by decomposers, which
release Nitrogen back to
the atmosphere
- Forms about
3% of the
human body
- Nitrogen cannot be
directly absorbed by
living things, it acts as
its chemically inert.
- Nitrogen is fixed in the
atmosphere by lightning,
biologically by some
bacteria and industrially
in human processes to
make fertilisers.
