How does coral get its energy?

When Charles Darwin saw the Great Barrier Reef during his voyage on the HMS Beagle in the 1830s he was confused. How could there be so much life in such clear water?

The beautiful clear water that we associate with the tropics is nutrient (food) poor. Cloudier water is full of small animals and algae that provide food. Tropical corals have developed a special relationship that allows them to thrive and support about a quarter of all marine life. The coral feeding game is a fun way of finding out how this all works.

The live lesson will focus on reviewing this activity and deepening understanding of coral feeding. It is expected that students will have completed the activity and viewed some of the multimedia before they join the live lesson.

Remember that questions and shout outs can be submitted up to 24 hours in advance for booked lessons via your user profile.


The live lesson assumes that students and families will have completed the Coral Feeding Game activity. There is an online diagram to reinforce this learning.

Then learn how to go on an underwater virtual reality journey to see how coral’s energy trick creates the habitat that supports 25 per cent of all marine life.
