Many have photosynthesizing algae within their tissue that produce oxygen. Dead coral also produces the foundation on which future generations of coral will live.
Coral Reefs
Most coral colonies reproduce by releasing eggs and sperm into the water simultaneously, a process known as broadcast spawning. This synchronized mass spawning event usually occurs once a year. Additionally, some coral species can reproduce asexually through methods such as fragmentation or budding.
The most famous polyp colonies are called, "Coral".
Sediments turn into coral reefs when coral colonies are formed over them, a process that can take thousands of years.

Coral makes up coral reefs. Coral by definition are microscopic animals with an outer skeleton of calcium carbonate that form colonies and are responsible for reef building.
A coral polyp is an individual coral cell, and when polyps stick together, they form coral a.k.a. Coral Polyp Colonies. Later, when the polyps die, their skeleton (which is like a hard shell) Strengthens the coral formation.
By breaking off and making new corals.
some coral reefs do live alone, but some live in groups called colonies.
Coral reefs come from living organisms and they form colonies of all sizes and shapes.
Yes it is I had to look it up for a science project.
Coral is the animal, coral is a living creature. Certain corals are made up of colonies of corals. For example, a plating coral (Montipora Cap.) can have hundreds or thousand of small animals living in one piece of coral.
