INTERDEPENDENCEAll living and non-living things in anecosystem are interconnected and
changingeven 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
Page 12
COMPETITIONIf 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 thepopulation= _____________

During this drought, there was not enough food available and many kangaroosstarved.
Page 14
REMEMBER: EVERYTHING IS CONNECTED !
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
When an ecosystem receives a LARGE inputof limiting nutrient (ie.,fertilizer runoff) thepopulation increases dramatically = ___________

The short supply of a limiting nutrient keeps the populationin check.
