WHAT IS A RESOURCE?Anything needed by an organism for life____________________________________________
Examples:

COMPETITION
FOOD
Organisms in an ecosystem have to compete with each other for available resources.

PREDATION

PREDATIONOrganisms in an ecosystem that
capture and eat other organisms to supply their energy needs

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
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= _____________LIMITING FACTOR
SHORT SUPPLYCYCLES SLOWLY
http://www.wspa-international.org/exhibition/gallery/large_DeadKenyan%20droughtSPANA.jpg
During this drought, there was not enough food available and many kangaroosstarved.
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.
BIOLOGY; MIller and Levine; Prentice Hall; 2006
LIMITING NUTRIENT
When an ecosystem receives a LARGE inputof limiting nutrient (ie.,fertilizer runoff) thepopulation increases dramatically = ___________
http://www.greenfacts.org/images/glossary/algae-bloom.jpg
The short supply of a limiting nutrient keeps the populationin check.
