598 words - 2 pages

Port Noarlungareef should essentially remain a reserve and not endangered by vile acts by humans. The unique Reef has been established for over 36 years, and is also one of Adelaide's main attractions.

Sponges, hydroids, and molluscs also inhabit various reef regions, as well as reef fish.The ecosystem of the reef is fairly straight forward.

The producers provide resourceful energy for organisms (Warreners, Elephant Snail, and Sea Urchin), in order for them to survive. These organisms are eaten by the marine carnivore organisms (Common Sea Star, Dog Winkle) for sufficient energy. Birds and Fish gain their energy by obtaining most of these heterotrophs and autotrophs. The characteristics of the ecosystem play a big part in order for the ecosystem to survive.Port Noarlunga reef should retain as a sanctuary. This reserve is unique to...
