Mercanlar birbirine ba\u011fl\u0131 milyonlarca k\u00fc\u00e7\u00fck canl\u0131 olan poliplerden meydana gelir. Her bir mercan polipi, kire\u00e7ta\u015f\u0131 (kalsiyum karbonat) salg\u0131layarak sert bir d\u0131\u015f iskelet olu\u015fturur. Bu polipler, birbirine ba\u011fl\u0131 koloniler halinde b\u00fcy\u00fcd\u00fck\u00e7e, zamanla geni\u015f ve sa\u011flam mercan resifleri meydana gelir. Bu s\u00fcre\u00e7, k\u00fc\u00e7\u00fck poliplerin kalsiyum karbonat salg\u0131layarak birbirine yap\u0131\u015fmas\u0131 ve \u00fcst \u00fcste birikmesiyle ger\u00e7ekle\u015fir. Sonu\u00e7 olarak mercan resifleri, binlerce y\u0131l s\u00fcren bu birikim s\u00fcreciyle deniz alt\u0131nda b\u00fcy\u00fck ve karma\u015f\u0131k yap\u0131lar olu\u015fturur. Gece boyunca aktif h\u00e2le gelen mercanlar, mikroskobik boyuttaki tek h\u00fccreli olan plankton ile k\u00fc\u00e7\u00fck bal\u0131klar gibi yiyecekleri yakalamak i\u00e7in poliplerinin dokuna\u00e7lar\u0131n\u0131 kullan\u0131r.<\/p>\n

Mercan resifleri, zengin besin kaynaklar\u0131na sahip ekosistemlerdir; bal\u0131klar, kabuklular, deniz s\u00fcngerleri, deniz analar\u0131 ve di\u011fer bir\u00e7ok deniz canl\u0131s\u0131 i\u00e7in koruma ve bar\u0131nma sa\u011flar.

Bu da daha b\u00fcy\u00fck bal\u0131klar ve di\u011fer deniz canl\u0131lar\u0131 i\u00e7in bir besin zinciri olu\u015fturur.<\/p>\n

Mercanlar\u0131n canl\u0131 renkleri, i\u00e7lerinde ya\u015fayan su yosunlar\u0131 (simbiyotik algler) taraf\u0131ndan sa\u011flan\u0131r. Bu su yosunlar\u0131 fotosentez yaparak mercanlara enerji sa\u011flar ve ayn\u0131 zamanda onlara renk verir.<\/p>\n

Mercanlar genellikle berrak, s\u0131\u011f sularda ve tropikal b\u00f6lgelerde bulunur. I\u015f\u0131\u011fa ve s\u0131cakl\u0131\u011fa kar\u015f\u0131 hassast\u0131r, bu nedenle su s\u0131cakl\u0131\u011f\u0131ndaki ani de\u011fi\u015fiklikler veya kirlilik mercanlar i\u00e7in b\u00fcy\u00fck bir tehdit olu\u015fturabilir. Stres alt\u0131ndaki mercanlar su yosunlar\u0131n\u0131 kaybeder ve bu durum “mercan a\u011fartmas\u0131” olarak adland\u0131r\u0131l\u0131r.
