17
When coral stress, then begin to kick out their zooxanthellae, what is happening?
Parasitism
coral bleaching
Coral dies
ocean acidification
18
Which of the following is a false statement about mangrove forests?
They reduce sedimentation and build up land
The cage like root system provides ecological advantages such as protection
They can survive in low oxygen, high salinity waters
Climate change is a benefit to humans because it increases sea level
19

27
Most of the animals living in the sandy intertidal are:
Burrowers

Attached to substrates
Producers
28
What is NOT an adaptation of the Red Mangrove to their environment?

30
What is NOT a reason Sandy shores have low biodiversity?
It is subject to increased sedimentation at times
They have an unstable substrate
It is subject to increased erosion at times
The have a lack of producers
31
The littoral zone is:

Area between lowest high tide and the highest low tide
Area between highest high tide and lowest low tide
Highest high tide and lowest low tide
32
What is NOT a way the Mangroves protect the coastlines?
Prop roots reduce erosion
Prop roots protect from wave action
Prop roots increase sedimentation
Prop roots provide nurseries for organisms
33
What biological factor can lead to reef erosion?

Barrier reef has a shallower lagoon and is closer the the shoreline
Barrier reef has a deeper lagoon and is closer to the shoreline
Barrier reef has a shallower lagoon and is further from the shoreline
38
The upper limit of an organism's distribution in the rocky intertidal is mostly determined by:

40
Why would it be advantageous to burrow oneself into the sand if you lived in an intertidal zone?
it would not be advantageous to burrow into the sand.
so you could get more oxygen
so you would not be carried away by the waves and tides
so you could make a bigger home
41
Describe how wave action can be beneficical to organisms in a tide pool
prevents desiccation
replenishes oxygen
increases salinity
