Questions with Detailed Verified Answers (100%
Correct Answers) /Already Graded A+
Lesson 4
Ans: Coral Reefs
v - coral bleaching
Ans: the result of zooxanthellae becoming damaged or dying, leaving the
white skeletons of the corals exposed
v- sedimentation
Ans: the setting of particles that are normally suspended in water against a
barrier
What describes coral reefs? (3)
Ans: - can retreat into its skeleton if needed to protect from predators
- sessile, or permanently attached to one spot, and exists their whole life in
the polyp stage
- live in colonies and because of the calcium carbonate skeleton, look like
rocks
The rate at which coral reefs grow depends on __________ of corals
making the reef.
Ans: the type
,Why are coral reefs found in shallow waters?
Ans: because they need enough light for photosynthesis to occur
Why are coral reefs called the rainforests of the ocean?
Ans: because so many species live in the cracks of the skeletons making
them one of the most diverse ecosystems on earth
Which type of algae has a symbiotic relationship with coral and why is
it important? (2)
Ans: - zooxanthellae
- The algae performs photosynthesis and provides the basis of the food chain
for the coral reefs ecosystem.
Which are the different types of corals? (3)
Ans: - Barrier reefs are separated from the shoreline by a bay or lagoon.
- Atolls are corals that sit on top of volcanoes that are submerged
underwater.
- Fringing reefs are located directly off the shorelines of continents and
islands.
What is the longest barrier reef? Where is it located? (2)
Ans: - Great Barrier Reef
- Queensland, Australia, in the Coral Sea

, Why are coral reefs important? (4)
Ans: - Coral reefs are important because they make up the most diverse
ecosystems in the ocean.
- Coral reefs are good indicators of environmental and ecological health.
- Coral reefs also protect their shoreline from erosion due to waves and
provide sand for beaches.
- Coral reefs are important economically due to their value to fisheries and
touristic attraction.
What are some of the organisms that live in the coral reefs? (3)
Ans: - sponges, jellyfish, crabs
- urchins, sea anemones and many fish
- shrimp, fungi, starfish
What is coral bleaching? (2)
Ans: - is the result of zooxanthellae becoming damaged or dying, leaving
the white skeletons of the corals exposed
- is caused by disease, too much shade, and therefore not enough light to
carry out adequate photosynthesis, changes in temperature, changes
in salinity, and sedimentation
What causes coral bleaching? (3)
