interdependence
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

competition5
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!

slide13
If a nutrient is in _____________OR __________________

it will LIMIT the growth of the

population= _____________

SHORT SUPPLY

CYCLES SLOWLY

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

slide14
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
LIMITING NUTRIENT

The short

supply of a

limiting

nutrient keeps

the population

in check.

When an ecosystem receives a LARGE input

of limiting nutrient (ie.,fertilizer runoff) the

population increases dramatically = ___________
