Ningaloo Reef Marine Ecosystem 1. Identify ten organisms from your chosen ecosystem and draw a food web to show trophic interactions between them. Within this food web, you must include and label a decomposer. Ten organisms that live in the Ningaloo Reef include the bottlenose dolphin, loggerhead turtle, tiger shark, whale shark, Southern Calamari squid, jellyfish, zooplankton, dugong, phytoplankton and seagrass. The decomposer in this food web is bacteria, which works to further break down…

the experience of these labs, comparisons can be made between many aspects of these two organisms. These aspects suited for comparison include the body plans and symmetry of starfish and crayfish, the science behind their need and ability to move, how each organism obtains oxygen and distributes it therefore throughout the body, the processes of their digestive and nervous system, and lastly how each organism reproduces and the pros and cons of their methods. Starfish are classified among the…

among fish and humans. For instance, modern day animals have vertebrae, being composed of a bony skull and backbone. The first organisms on earth to have a bone-like structure are fish.

This is direct proof of the common ancestor. The most common homologous structure is the arrangement of the limbs of…
