These questions are prepared to give you the opportunity to draw on the widest possible sources you may have available at your disposal. Students are encouraged to discuss these questions amongst themselves prior to the examination. Marine Our explorations of rocky shores revealed some apparent patterns in the distribution of organisms and their responses to the physical environment. Describe, compare and contrast the habitats, fauna and flora of intertidal rocky shores of Polka Point and Lady Elliot Island. Australia's marine biota is among the most diverse on the planet.
Marine environments are particularly rich in examples of intricate relationships between organisms.
Such relationships may range from low order interactions where animals merely occupy the same environment to higher order interactions where animals live in very close, sometimes obligate, association. Discuss, with examples, symbiosis in marine systems. Terrestrial Australia is often considered to have unique fauna and flora because of its apparent age. Briefly discuss attributes of typical Australian animals that make them different from animals of other continents. Compare and contrast three Australian plant communities discussing how they differ and suggesting why these differences might occur.
