What happens when the food web changes
What Happens When The Food Web Changes? which organisms transfer energy by being eaten


What happens when the food web changes1
What Happens When the Food Web Changes? which organisms transfer energy by being eaten

  • Everything is connected in an ecosystem

  • If one part of the food web changes it has a domino effect on the other species

  • Can cause increase and decrease in other populations

  • Is one species more important than another?

Interdependence
INTERDEPENDENCEhttp://www.dimijianimages.com/Aggression-defense-page4/vultures.jpg

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
COMPETITIONhttp://www.dimijianimages.com/Aggression-defense-page4/vultures.jpg

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 _____________http://www.dimijianimages.com/Aggression-defense-page4/vultures.jpgOR __________________

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


REMEMBER: EVERYTHING IS CONNECTED !http://www.dimijianimages.com/Aggression-defense-page4/vultures.jpg

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 NUTRIENThttp://www.dimijianimages.com/Aggression-defense-page4/vultures.jpg

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 = ___________
