A food web consists of all food chains of an ecosystem. A food web is a diagram which shows the transfer of energy between species. Energy is transferred through food; therefore, food webs basically show which fauna eats which. Food webs are organized into layers of who eats who called trophic levels. The bottom trophic level of a food web is the producers, the second being the primary consumer, then the secondary consumers, tertiary consumers and the final trophic level being the decomposers. The ecosystem of the Great Barrier Reef is a fragile balance, with a food chain that has several points, in which each one is reliant on one another. The Great Barrier Reef’s coordinates are 18.2871° S, 147.6992° E. The Reef has a huge amount of flora
Invasive species are “species that is non-native to the ecosystem whose introduction is likely to cause economic and environmental harm”. A example of Invasive species would be the Zebra Mussel. Zebra Mussels or also known as Dreissena polymorpha is a small freshwater mussel. The Zebra Mussels can live up to three-nine years which can grow up to 2 inches. These mussels attach to hard surfaces such as rocks or boats. They were first introduced to the Great lakes in 1988 but were originally from Russian and Ukraine lakes. The Zebra Mussels were first found in Lake St. Claire (one of the 5 great lakes) which within one year they rapidly spread to almost all of the Great Lakes except Lake Superior. This is because Lake Superior is not the ideal
For many it’s a first pet, a gift from family, something you won as a prize at a carnival, but for Canadian residents the familiar orange goldfish everyone knows and loves is becoming a serious problem. Some flush them in a hurry because they no longer want to take care of them, others commit them to a porcelain vortex because they believe their beloved fish has passed, and the Canadian Government is issuing a warning now to citizens of Canada to stop flushing their fish.
The three spined stickleback fish has many unique traits. some of the most notable structural adaptive traits of this specie are the three spines and body armor. The three spines are sharp and located on the back forward of the dorsal fin. The lateral bony plates are located on each side of the body. These structural armors projecting from the back and pelvis can simultaneously flare out when the fish feels threatened as a defense against predatory vertebrates making it difficult for predators to swallow them. With the back spines pointing directly upward and the pelvic spine pointing out at a perpendicular angle make it difficult for a predatory fish that catches a stickleback to swallow the stickleback. This added benefit allows the fish
Coral bleaching is not just a national problem that Australia faces alone. In the last year (2015), 12 percent of the world’s coral reefs have bleached (Howard). Since the Great Barrier Reef is the world’s largest reef, covering 133,000 square miles, and stretching 1,200 miles along the coast of Australia, it poses an incredible threat to Australia’s economy and environment (Howard). Coral bleaching is not an issue that is often plastered all over the news or brought to people’s attention often. Coral Reefs, especially the Great Barrier Reef are seen as the perfect tourist destination because reefs are known for their wide variety of marine life and beautiful bright corals one would see on brochures. However, when a coral is bleached, it loses
Great white sharks are the biggest predatory fish in the ocean and they can grow to about 15 feet in size, although larger than 20 feet have been seen. Their name comes from the white underbellies of the sharks and their bodies are designed to blend in with the seabed. The great whites have powerful tails which makes them excellent swimmers that can travel up to 24 km/h. They have many rows of triangular shaped teeth and have a great sense of smell and even their body can sense electromagnetic fields produced by animals. They mainly eat sea lions, small toothed whales and sea turtles. These sharks can be found in cold coastal waters around the world, scientists are not sure how many
Blackfish, a documentary by Gabriela Cowperthwaite, a historically observed impact of the captivity of killer whales. This Documentary focuses on the orca Tilikum, who was captured off the coast of Iceland. On February 21, 1991, Sealand trainer Keltie Byrne fell into the pool with Tilikum. She was pulled to the bottom by Tilikum, tossed around, and drowned. It took Sealand employees two hours to recover her. She was the first to have been killed because of Tilikum’s stress, frustration, and confinement. Sea Land of the Pacific in Victoria, Canada and SeaWorld in Orlando, Florida tries to explain Tilikum’s aggressive behavior as a result of his restricted life in the marine parks. this topic will soon becomes the documentaries biggest claim. supporting this, Blackfish sets up
The documentary Blackfish, directed by Gabriela Cowperthwaite released in July 2013, explores the mistreatment of killer whales and the relationship between the killer whales and trainers as well as the significant problems of the sea-park industry, with a focus upon SeaWorld. Cowperthwaite positions the audience to feel sympathy towards the killer whales by making deliberate choices in sound, visual, language, and structure through the representation of trainers as unprofessional, and whales as mistreated, also experts as reliable information source.
The Great White Sharks, known mostly because of their white underbellies, are one of the most powerful aquatic animals in the world. They can swim at about 25 Miles Per Hour (40 Kilometers per hour) because of their strong muscles and forceful tails. In addition to that, male Great Whites can grow around 11.5 to 13.1 feet long, while females can grow from 14.8 to 16.4 feet long. This paper will demonstrate how Great White Sharks are an important part of their ecosystem, how their diets work and will adequately describe their habitats.
Intruding on the fresh water of six US states, roams the scaled head, large mouth, razor sharp teeth and protruding lower jaws of the Snakehead Fish. The life cycle of The Snakehead fish begins between June and July when females begin spawning. The female fish may lay up to 15,000 eggs one to five times per year. After 1 to 2 days, the eggs will hatch and be guarded by both parents. They feed on small crustaceans and fish larvae. Young may be golden brown or pale gray, darkening as they grow older, reaching sexual maturity at 2 years old.
In order to fully analyze this great loss, we must first understand what the Star Tiger is and how it came to existence.
To some cooks, Fleur de sel is an overpriced and unnecessary ingredient marketed to the gullible and the pretentious; to others, it is the source of the uniquely clean and briny salinity sought after by lovers of fresh seafood. It is widely considered to be among the very best finishing salts, which means that you should keep it on hand for sprinkling onto food just before serving. If you cannot find fleur de sel near you, there are still options that will provide much of the same benefits. Consider the fleur de sel substitutes below.
Animalia, Bilateria, Deuterostomia, Chordata, Vertebrata, Gnathostomata, Osteichthyes, Actinopterygii, Neopterygii, Teleostei, Acanthopterygii, Perciformes, Percoidei, Coryphaenidae is a family of Dolphinfishes. They are widely known by their vibrant turquoise, blue, green, and yellow colors primarily in the males. Major species of Coryphaenidae include Mahi Mahi and Pompano Dolphinfish. Mahi Mahi translates to very strong in Hawaiian. Ranging from North Carolina down the coast south of Florida, Mahi is a very prized sport fish. Many fishing competitions take place often. A lot of expensive seafoods are counterfeited by using different seafood as a substitute. For example, Japanese people sell skate wing instead of scallops because they have very similar texture. Imitation crab has also been sold instead of actual crab because it’s easier and cheaper to produce and sell. Since swordfish are very expensive, Pompano Dolphinfish is used as a very cheap alternative to
According to world wildlife organisation, overfishing occurs when more fish are caught than the population can replace through natural reproduction. Gathering as many fish as possible may seem like a profitable practice, but overfishing has serious consequences. The results may not only affect the balance of life in the oceans, but also the social and economic well-being of the coastal communities who depend on fish for their way of life.
The term ‘processed food’ applies to any food that has been changed from its natural state in some way, either for safety reasons or convenience. Some foods need processing to make them safe, such as milk, which needs to be pasteurized to remove harmful bacteria. Other foods need processing to make them suitable for use, such as pressing seeds to make oil.
