Question

How are corals made? Example; the Barrier Re if.?

Answer 1

corals aren't "made". they are born. they are living organisms. alive. they are like plants that suck there food from the water around them. they release spores that drift off and land and grow. however the reason coral reefs are in so much danger, is because they are very delicate and die easy. most corals also don't grow very well. they are slow. so when you add up pollution, lowering fish populations, and human interference, you get lots of destroyed reef systems. and without reefs our oceans will die.
