Organisms in an ecosystem have to

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!
If a nutrient is in _____________
OR __________________
it will LIMIT the growth of the
population
= _____________
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
population increases dramatically = ___________

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.
