11. Food Webs:
- the connection of several
food chains.
- more realistic view of
energy transfer.
- show organisms as part of
an interlocking relationship.

Name an organism that:
- eats rabbits
- is on trophic level 2
- is an autotroph
- is a top carnivore
19. Impacts on Food Webs
What would happen if an organism in a food chain
suddenly has a drastic change in population?
20. Think. Pair. Share.
What would happen if all
of the mangroves in
this ecosystem were
cut down by
humans?
There would be no food
for the fish or crabs
to eat, so they
would all die off.
After the fish and crabs
die, the seabirds and
pied oyster catchers
would also starve.
21. Think. Pair. Share.
What would happen if a
virus invaded this
ecosystem and
killed-off all of the
seabirds?
There would be no
predators to eat the
fish and the fish
population would
become very large.
If there are too many fish
in the ocean, they
may out-compete the
pied oyster catchers
for crabs and drive
them to starvation.
