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.
