While I was doing research, I identified the species I found. The primary producers were Nori Seaweed, Black Pine, and Coral Weed. The sessile consumers consisted of Mussels, Acorn Barnacles, and Goose Neck Barnacles. The mobile consumers happen to be Whelks, Chiton, Starfish, and Green Crabs and they
One amazing species (Birgus latro) can climb coconut trees, cut a coconut loose, and can make a hole in a coconut so it can eat the inside! (I'm not making this up!) They do all have to return to the water to reproduce however. Did you know that hermit crabs are not considered true crabs? Two big differences are seen in the legs and the antenna.
(NOAA) Though these mollusks play an important role in estuaries, they also play an important role on land economically through the harvesting and selling of them for food. An area that has been most effected by Eastern Oysters is the waters of the Chesapeake Bay. For centuries, the Eastern Oyster cleaned and protected the waters of the Chesapeake Bay, providing habitat for its fishes and crabs. In the 17th century, one of the bay’s first European explorers, Captain John Smith, described the oysters as “laying thick as stones” and even made a note that the waters were difficult to navigate because there were so many oyster reefs. (Chesapeake Bay.net) With that being said, it isn’t a surprise that the Chesapeake Bay literally translates to “great shellfish bay”, but it would not hold this title for long.
Some are unicellular and some are multi cellular. Bacteria is a large group of single celled organisms that are found in every corner of the earth, be it land, air or water. Viruses are parasites which means they can cause harmful diseases such as small pox. (www.sciencedaily.com/articles/m/microorganism.htm) Algae are another diverse group of plants that may be unicellular or multi-cellular but are autotrophic. Diatoms are type of algae , found in toothpaste, they can be classified into two groups called centric and pennate.
Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions. Competition with other organisms, availability of food and predation can also affect the abundance and distribution of rock-shelf organisms. To determine the abundance and distribution of these rock-shelf organisms a quadrat with an area of 0.5m2 was used. It was placed randomly in each location. Location 1 was above the high tide mark, Location 2 the tidal rock pools and location 3 the low tide mark.
Evaluate the relative importance of global and local threats to one named global ecosystem (15 mark) One named global ecosystem is the coral reef. In order for an ecosystem to be a coral reef they would need to be in certain conditions; it usually is where the temperature is around 24 degrees and be in water less than 25m depth. The Coral reef has many global and local threats. The coral reefs are homes to over 25% of known sea creatures and are an invaluable service for the local population as a source of food and income. One major threat is that coral reefs are under huge stress due to the impact that human activities are having and in fact already 1/5 of the world’s coral reefs are so damaged that they are beyond repair.
Sea urchins and humans share more than 7,000 genes, and biologists are now using these sea creatures to unlock the mysteries of human diseases. In fact, there are several genes in the sea urchin involving Alzheimer's, Parkinson's disease, muscular dystrophy and many other

Their lungs lie across the arched ribs along the full length of their vertebra, almost to their anus, instead of along its rib cage (ventral) like most mammals. This helps with buoyancy and balance. Each long, wide but thin lung has its own cavity with its own diaphragm. Scientists don't know if they can function independently, but they do know that manatees can have a severe infection in one lung and be healthy in the other lung. This helps with buoyancy and balance.
Completely ridding an infested habitat of zebra mussels is nearly impossible with the technology and knowledge available today. So, what makes sense economically speaking? While implementing precautionary measures to ensure mussel prevention may seem economically inefficient, this is an efficient strategy because of the maintenance costs required in an infested habitat of zebra mussels. Once the mussels overtake an area, millions of dollars are necessary to control to species to a confined area. Environmental organizations are even funding prevention plans where infestation has not yet taken place.
