How does Matter move
through an ecosystem?
1.
 Unlike the one way flow of
energy, matter is recycled 2.
within & between
ecosystems
 Nutrients are passed
between
organisms & the environment
through biogeochemical
cycles
 Biogeochemical Cycles:
 Bio –life
 Geo – Earth
 Chemo – chemical
WATER CYCLE
NUTRIENT CYCLES:
a) CARBON
CYCLE
b) NITROGEN
CYCLE
c) PHOSPHORUS
CYCLE
Why are nutrients
important ?
 Every living organism
needs nutrients to
build tissues and
carry out essential
life functions.
95% of your body is made of…
1)
OXYGEN
2)
CARBON
3)
HYDROGEN
4)
NITROGEN
Availibility of nutrients
 If a nutrient is in short
supply, it will limit an
organisms growth. It is
called a limiting nutrient
 When a limiting nutrient
is dumped into a lake or
pond, an algal bloom
occurs and can disrupt
the ecosystem
THE WATER CYCLE
CARBON CYCLE
4 PROCESSES MOVE
CARBON THROUGH
ITS CYCLE:
(see fig.3-13)
CO2
1) Biological
2) Geochemical
3) Mixed biochemical
4) Human Activity
CO2
NITROGEN CYCLE
14)
(see fig.3N2
in Atmosphere
Nitrogen-containing nutrients in
the biosphere include:
1) Ammonia (NH3)
2) Nitrate (NO3-)
3) Nitrite (NO2-)
ORGANISMS NEED
NITROGEN TO MAKE
AMINO ACIDS FOR
BUILDING PROTEINS!!!

PHOSPHORUS CYCLE
(see fig.3-15)
PHOSPHORUS FORMS PART OF IMPORTANT LIFE-SUSTAINING
MOLECULES (ex. DNA & RNA)
