Reef Relationships

Course Access: Lifetime
Course Overview

STEMLinc Video Conferencing: The Great Barrier Reef Marine Park is more than just coral reefs. Join us to discover a variety of ecosystems that are found there. Develop an understanding of the inter-relationships between the organisms that can be found in different ecosystems including predator-prey interactions, and symbiotic relationships. Investigate how changes in biotic and abiotic factors arising from human activities can affect feeding relationships in these ecosystems, including how poor water quality increases algal growth, and population outbreaks of coral eating Crown-of-thorns starfish.
