Which is a characteristic of coral reefs?

Answer 1

high biodiversity

Answer 2

Well here are some facts about the coral reef:

• coral reefs are like many rainforests,only under water
• when the reef drops about 50 ft.and for many reef fish who find shelters on the cliff the reef face is the zone above the reef floor or reef drop
• the reef flat-sandy bottomed flat can be behind the main reef,containing chunks of coral
• the reef lagoon "many coral reefs completely enclose an area",there by creating a quite water lagoon

Thanks for coming!

Answer 3

There are both hard corals and soft corals, which fall into three types of coral reefs. Fringing reefs form along Coastlines, growing in shallow water along a continental shelf. Barrier reefs grow further out in the ocean, but are still parallel along the shoreline. Coral atolls grow in rings atop long forgotten volcanoes deep in the ocean. They begin their life as fringe reefs, and then continue to grow as the volcano begins to sink until all that remains is the reef itself

Answer 4

Coral reefs are primarily made from the limestone structures made by coral polyps. Coral polyps are colonial animals that secrete calcite exoskeletons (called corals) to protect themselves. Over time these corals accumulate one on top of another to form a reef that reaches from depth to the surface. The reef is a habitat for great varieties of other marine life much of which feeds on the corals, excreting their hard parts as sand (coral sand) and it is this sand which fills in the gaps between the corals as the reef builds up.

Answer 5

Coral reefs are made by Coral polyps which eats zoo plankton

Answer 6

Answer 7

Marine biome.
