Feeding Guilds

The "[relationship] between different organisms can be described by their trophic associations." On the most fundamental level, trophic associations describe "what an organism eats and what eats it."[1] All organisms can be divided into three different categories: producers, consumers, and decomposers. [1][2]

Autotrophs

Autotrophs are "self-nourishing organisms capable of absorbing solar energy and photosynthetically building high-energy organic substances" [1] A classic example of an autotroph on the reef are zooxanthellae. Autotrophs are the primary producers in the marine environment.

Heterotrophs

Heterotrophs are consumers that feed upon other organisms.

= Herbivores

Herbivores feed directly upon autotrophs.

Carnivores

Carnivores feed upon other animals.

Omnivores

Omnivores consume both autotrophs and other heterotrophs.

Detritivores

Detritovores are decomposers like bacteria that feed upon the waste products and dead remains of other organisms. [1]

Filter/Suspension feeders

Planktivores

Opportunistic feeders

Parasites
