and eat other organisms to supply their
energy needs

INTERDEPENDENCE
All living and non-living things in an
ecosystem are interconnected and changing
even one thing impacts the whole ecosystem.
When one tugs at a single thing in nature,
he finds it attached to the rest of the world.
~John Muir, naturalist, Sierra Club founder
COMPETITION
If resources are scarce, some organisms
will starve and populations will decrease.
If resources become more plentiful,
populations will increase.
Competition in nature often results
in a winner and a loser
. . . with the loser failing to survive!
SHORT SUPPLY
If a nutrient is in _____________
CYCLES SLOWLY
OR __________________
it will LIMIT the growth of the
population
LIMITING FACTOR
= _____________
During this drought,
there was not enough food
available and many kangaroos
starved.
http://www.wspa-international.org/exhibition/gallery/large_DeadKenyan%20droughtSPANA.jpg
REMEMBER: EVERYTHING IS CONNECTED !
BIOLOGY; MIller and Levine; Prentice Hall; 2006
A decrease in the prey population means some predators will starve.
Fewer predators mean prey population will increase.
Increase in prey means more food for predators.
Predator population will increase until there is not enough food . . .
and the cycle repeats itself.
LIMITING NUTRIENT
The short
supply of a
limiting
nutrient keeps
the population
in check.
http://www.greenfacts.org/images/glossary/algae-bloom.jpg
When an ecosystem receives a LARGE input
of limiting nutrient (ie.,fertilizer runoff) the
BLOOM
population increases dramatically = ALGAL

3 KINDS of SYMBIOSIS
______________________
MUTUALISM
Both organisms benefit
COMMENSALISM
______________________
One organism benefits;
Other is neither harmed nor helped
_____________________
PARASITISM
One organism benefits;
Other is harmed in some way
MUTUALISM
“Good for me - Good for you”
Birds eat parasites living
on the hides of giraffes and
rhinos while enjoying
protection from predators.
Groomed animals lose their
pests.
http://www.imbt.org/science.htm

Insects transfer pollen
between plants as they
gather nectar for food.

MUTUALISM
“Good for me - Good for you”
Clown fish gets protection from enemies
by hiding out in poisonous sea anemones
Sea anemone gets
scraps of leftover
food dropped
by fish
http://www.zahnersatz.com/english/library/symbiosis.jpg
COMMENSALISM
“Good for me - Doesn’t bother you”
http://www.geology.wmich.edu/gillespie/g322/Chapters/C16shark.gif
Pilot fish receive scraps of food dropped by shark;
Shark is neither harmed nor helped
COMMENSALISM
“Good for me - Doesn’t bother you”
http://www.abyssal.com/meeks/images/hermit_crab.jpg
Hermit crabs make homes in shells abandoned by snails;
Snail is not harmed by crab
PARASITISM
“Good for me - Hurts you”
http://www.geology.wmich.edu/gillespie/g322/Chapters/C16parasitism.whale.gif
Barnacles are crustaceans that attach to the surface of whales
and feed on their skin and fluids; Whale is harmed
PARASITISM
“Good for me - Hurts you”
http://www.dogbreedinfo.com/guineafowltickphotos.htm
Tick feeds on dog’s blood;
Dog has discomfort, can get diseases/infection from bite

ENERGY & MATTER
Energy is not the only thing
that moves through the ecosystem.
Atoms are never destroyed . . . only
transformed.
Take a deep breath.
The atoms you just
inhaled may have been
inhaled by a dinosaur
millions of years ago.

4 ATOMS make up 95% of the
body in most organisms
OXYGEN
CARBON
HYDROGEN
NITROGEN

PHOSPHORUS CYCLE
Producers absorb
phosphate from
soil and water
Weathering wears
away rocks and
sediments and
releases phosphate
into soil and water
Sediments form “new land”
to complete cycle
Phosphate moves
through food web
Phosphate returns to
soil and water from
waste or decomposition
Phosphorus cycle
is only biogeochemical
cycle that does
NOT cycle through the
atmosphere

IMPORTANT?
