Describe zonation in intertidal rocky bottoms
Question 13
13.
List the four challenges that organisms have to face for survival in the rocky intertidal zone. Next, list one way in which the organisms have adapted to that challenge.
The intertidal zone ecosystem is found:
on the edge of a pond
on the beach by the ocean
on the shores of a lake
on the banks of a river
The spray zone is all these things except
high up on the beach
underwater
get sprayed by big waves only
is like a desert
The upper intertidal zone is all these things except
never out of the water
a very salty area
has sea anemones, crabs, starfish, snails, barnacles and mussels
underwater only when the tide is high
The middle intertidal zone is all these things except
spends half its time underwater
is the calmest zone
where you start to see seaweed
gets the fiercest wave action
The lower intertidal zone is all these things except
has tones of wildlife
is mostly underwater
gets dry only for a short time during low tide
has no wildlife
All of these are animals you might see in the intertidal zone except
barnacles, limpets and mussels
whale sharks and giant squid
sea anemones and cucumbers
hermit, razor and green crabs
All of these are plants you might see in the intertidal zone except
daisies
kelp
seaweed
green algae
In which zone might you build a sand castle
the upper intertidal zone
the middle intertidal zone
the spray zone
the lower intertidal zone
Competition for which resource is a dominant ecological factor in the rocky intertidal?
oxygen
light
food
space
Which is a considered a keystone predator in the middle intertidal zone?
