Algae use sunlight to make glucose and fungus uses this as food, in turn fungus shelters the algae.
These fish are found swimming beneath sharks feed on scraps left over sharks meals
Herbivores eat plants, algae, and other producers. Many types of small crustaceans and turtles are herbivores that eat algae and sea grass. Also, sea urchins are powerful primary consumers in kelp forests.
Victoria’s marine waters cover some 10,000 square km including waters adjacent to the open ocean and Victoria’s bays, inlets and estuaries.

Relationship between organisms where one organism (a parasite) lives or feeds on the other, usually causing harm.
Animal that hunts other animals for food. A layered pyramid is used to describe not only the relationship of larger predators feeding on smaller animals (top down) but also how the triangular shape represents the reproductive rates (from slow-reproducing top predators down to more prolific prey, like feeder fish or plankton).
It is an ecosystem in which water has more than 50 parts per thousand of dissolved salts. Here plants and animals interact with the chemical and physical features of the environment.
