2 Reef Food Webs A food chain shows the transfer of energy (food) between animals and plants. For example a simple food chain might show an arrow going from grass to a cow to a human, demonstrating who eats what. A food web shows many different food chains interlinked. The following shows how quite a complex food web is constructed using the marine organisms you have been studying.

3 Which organisms get energy from the sun? Sun

4 Coral and zooxanthellae! Algae! Plankton! Sun

5 Coral and zooxanthellae Algae Plankton Which fish eat coral? Sun

6 Coral and zooxanthellae Algae Plankton Parrotfish! Sun

7 Coral and zooxanthellae Algae Plankton Parrotfish Which fish eat algae? Sun

8 Coral and zooxanthellae Algae Plankton Parrotfish!Damselfish! Sun

9 Coral and zooxanthellae Algae Plankton ParrotfishDamselfish Which fish eat plankton? Sun

10 Coral and zooxanthellae Algae Plankton ParrotfishDamselfish! Sun

11 Coral and zooxanthellae Algae Plankton ParrotfishDamselfish Which fish eat parrotfish and damselfish? Sun

12 Coral and zooxanthellae Algae Plankton ParrotfishDamselfish Coral Trout! Sun

13 Coral and zooxanthellae Algae Plankton ParrotfishDamselfish Coral Trout Which fish eat parrotfish, damselfish and coral trout? Sun

14 Coral and zooxanthellae Algae Plankton ParrotfishDamselfish Coral Trout! Sharks! Sun

15 Coral and zooxanthellae Algae Plankton ParrotfishDamselfish Coral Trout! Sharks Which animals feed on the dead and dying plant and animal matter keeping the marine environment clean? Sun

16 Coral and zooxanthellae Algae Plankton ParrotfishDamselfish Coral Trout! Sharks Clams! Crayfish! Sponges! Dead and Decaying Sun
