The reef covers an area over 300,000 square kilometers and includes a wide range of ocean depth, and it contains such biodiversity as to make it one of the most complex ecosystems on Earth. Within any given ecosystem, there are biotic and abiotic factors. 18 - 30°C and it also explains why most coral reefs are found between 30°N and 30°S around the equator. 2019 1. Corals can occur in salinity range from  32 -40 PSU, although coral reefs can thrive in both high or low salinity conditions. Coral is the basis for the diverse animal and plant life in the Great Barrier Reef. Explain the process of “coral bleaching.” This video provides an overview of corals. reef ecosystem. While abiotic factorshave more to do with inanimate materials and elements, such as water, oxygen, sand, rocks and shells, the biotic factor of coral reefs has to do with the various creatures that inhabit the ecosystem and are part of the food web. Another factor is salinity which is the amount of salt that is in the water. Source: quora.com. Plants and bacteria are two other major biotic components of the Great Barrier Reef.
