Cycles in the Enviroment
- As we and other
animals breath
,gasses are being
recycled by other
organisms
- When a tree dies
,it decomposes
and is recycled
back into the earth
- The Carbon Cycle
- micro plants,
animals and other
organisms called
plankton have
some carbon in
them ,that is what
fossil fuels are
made of
- phytoplankton
are plankton
that use the
sunlight to
make their own
food
- over time
plankton under
great pressure
will change into
fossil fuels that
contain carbon
from its original
organism
- the circulation of
carbon around an
ecosystem is called
the carbon cycle

- The Water Cycle
- water is required by
all living organisms
and moves around the
environment changing
form from air to the
ground to your body
- the water
cycle is a
continuous
movement of
water through
an ecosystem
- The 4 main processes in the
water cycle are ...
Evaporation: When liquid
changes into water vapor
Transpiration: When water is
taken by plants roots and
evaporates through it's
leaves Condensation: When
water vapor collects and
turns back into a liquid
Precipitation: When
condensation builds in clouds
then is released into snow,
rain hail,sleet
- there is also
Groundwater:
water that is the
soil, plants roots
can grow down
and reach
ground water
and humans can
dig Run-off:water
that runs off the
ground into rivers
lakes or streams

- Pollution In the Environment
- pollution occurs
when a substance is
added at such a fast
rate that it cant be
broken down, stored
or recycled so it
causes pollution
- substances that occur naturally can also become pollutants
cause if they are present in too high of an amount for the
environment to absorb without ahrmful affect for example
carbon dioxide occurs naturally however the buning fossil fuels
is damageging the enviorment , acid rain is amd ewhen
pollutants containing sulfur and nitrogen are found at high
levels and mix together making something acidic wher lakes
can be damaged and fish can't live because ph level is below 5
- the ph level measures
how acidic a liquid is
- pollution occurs
when a substance is
added at such a fast
rate that it cant be
broken down, stored
or recycled so it
causes pollution
- The Movement of pollution
- pollutants like pcb's are
moving through our
environment they are
substances used in paints and
and packaging there is also
mercury and ddt (pesticide)
these can be leaking into the air
water or ground through waste
disposal sites

- Bioaccumulation
- pollutants are stored in the same way
food and energy bare stored,
bioaccumulation oocurs when pollutants
enter the food web and accumulate in
high level consumers by eating
something that has pollutants in it.
example :pollutants-tiny fish-small
fish-large fish-humans
