Main predators of the great barrier reef
The reef shark is known as the main predator in the great barrier reef including the other sharks.
Sharks, such as tiger, hammerhead, bull sharks and the reef shark.
The black tigerfish is also a predator of the great barrier reef.
Energy flow
Plants and algae convert light energy into chemical energy, which then gets passed through the food web to plant eaters, and flesh eaters.
Biotic and Abiotic
Abiotic: sunlight and temperature are the main two abiotic factors. Including, buoyancy, viscosity, light penetration, salts, gases, and water density.
Biotic: Biotic factors are living components, including, coral, animals, planks like seaweed and plankton, and bacteria.
