Horses and donkeys are different species.
If you breed them, the result is a mule
which can NOT have offspring!

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

______________________
MUTUALISM
Both organisms benefit
COMMENSALISM

PARASITISM
One organism benefits;
Other is harmed in some way
MUTUALISM
“Good for me - Good for you”

rhinos while enjoying
protection from predators.
Groomed animals lose their
pests.

Clown fish gets protection from enemies
by hiding out in poisonous sea anemones

scraps of leftover
food dropped
by fish

Shark is neither harmed nor helped

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
PARASITISM
“Good for me - Hurts you”
Tapeworms absorb
food by living inside
host intestine;
host is harmed
