4
Describe how wave action can be beneficical to organisms in a tide pool

6
The upper limit of an organism's distribution in the rocky intertidal is mostly determined by:
pH levels
Grazing
Dessication
Salnity
7
The littoral zone is:
Area between high and low tide

8
Feature B of a polyp?

Stomach
Mouth
9
Which of the following is a false statement about mangrove forests?
They can survive in low oxygen, high salinity waters
They reduce sedimentation and build up land
The cage like root system provides ecological advantages such as protection
Climate change is a benefit to humans because it increases sea level
10
What is NOT a disadvantage for organisms that “clam up” during low tide?
increase of carbon dioxide
interrupted feeding
desiccation
gas exchange
11
Feature C of a polyp?
Tentacles
Stomach
Mouth
Nematocysts
12
What is NOT a physical factor that coral need for growth?
Basic pH
Sandy substrate
Temperature around 23°C
Water clear of silt & nutrients
13
What primary abiotic factor(s) are used to distinguish the zones of the open ocean?
Depth
Light
Pressure
Amount of food
14
Organisms have very few adaptations for living outside water.
Upper shore
Lower shore
Middle shore
Splash zone
15
What is the meaning of epipelagic
Bottom layer of the ocean no light penetration
Second layer of the open ocean with light penetration
In the first 200m of the open ocean with max light penetration
Middle layer of the ocean with low oxygen
16
What is the 2nd stage of an Atoll formation
Fringing reef is formed.
Barrier reef is formed
Volcanic Island emerges
Lagoon is formed
17
Why would it be advantageous to burrow oneself into the sand if you lived in an intertidal zone?
so you could make a bigger home
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
18
Which zones of the ocean have enough light for organisms to see each other
Bathypelagic
Epipelagic
Abyssalpelagic
Mesopelagic
19
Most of the animals living in the sandy intertidal are:
Attached to substrates
Producers
Burrowers
Plants
20
Which features describe hard corals?
Resemble plants, trees or fans
Have calcium carbonate skeletons
Have relationship with zooxanthellae
Reef builders
21
What is an adaptation of intertidal organisms that help with temperature and tide changes?
Have light color shells
Shrinking
Have dark color shells
Burrowing
22
Feature A of a polyp?
Stomach
Nematocysts
Tentacles
Mouth
23
What abiotic factors can lead to reef erosion?
COTs
Sediments
Storm damage
high pH
24
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
25
Which is NOT a condition that allows for successful growth of coral?
Alkaline pH
Soft substrate for attachment

Warm temperatures
26
What happens in the 4th stage of an Atoll formation
Barrier reef is formed
