What are some heterotrophs examples in the great barrier reef?

Some examples of heterotrophs in the Great Barrier Reef include various fish species, such as clownfish and parrotfish, which feed on algae and other marine organisms. Additionally, sea turtles, like the green sea turtle, consume seagrass and jellyfish, while invertebrates like sea stars and certain types of coral also rely on consuming organic material. These organisms play a crucial role in the reef's ecosystem by contributing to nutrient cycling and maintaining biodiversity.
