Seaweek 2010: Oceans of Life - ours to explore; ours to restore


• In an ecosystem there are many different living organisms that interact with each other in many different ways.

• Predator and prey interactions are key relationships on the reef as this is when energy is transferred from one organism to another.

• A food chain is defined as the interrelationship among animals and plants concerning the transfer of energy (food).

• There are many food chains that exist on the reef and together they form food webs. A food web is defined as the complex network of many interconnected food chains and feeding interactions.
