Some predatory fish are active hunters that will either chase down prey, like sharks, or wait for the food to come to them.

Is a fish a producer or consumer?
In aquatic ecosystems fish are often the organisms at the top of the food chain. They are often the secondary and tertiary consumers. The producers in an aquatic ecosystem are algae and aquatic plants.
What type of consumer are small fish?
