the chemicals that gets released when it breaks down. Bisphenol A is a chemical that is harmful to marine animals in a number of ways. For example‚ algae gains it’s nutrients through absorption. Algae can absorb bisphenol A‚ which will affect the entire food web in the end. Small fish tend to eat algae and zooplankton‚ and when a fish consumes algae that has absorbed bisphenol A‚ the concentration of the chemical will increase for the fish through a process called bioaccumulation‚ which causes the

tropics. As the name suggests‚ corral reefs are formed by colonies of coral polyps. Coral polyps secrete calcium carbonate (limestone) which forms the reefs. The polyps receive oxygen and nutrition through photosynthesis preformed by zooxanthellae algae. The necessity of large amounts of sunlights further restricts the environments in which these reefs can flourish. Reefs develop into three different formations. Fringing reefs occur along shorelines‚ and are frequently found on Hawaii and the Caribbean

that were located were found in the littoral zone of Bridgewater’s rocky seashore. A littoral zone is made up of a community of aquatic organisms habiting the narrow strip of coast. The organisms that were studied included periwinkles‚ sea stars‚ algae‚ urchins and different types of sea weed. Periwinkles have shells to reduce water loss and radiation effects. Sea stars also have a thick‚ impermeable outer layer to reduce radiation effects. Urchins are able to seek small crevices for shelter to reduce

Exploration of the digital world My chosen research topic is the natural dietary supplement Spirulina. Spirulina is a simple one-celled microscopic blue-green algae with the scientific name of “Arthrospira platensis”. It is grown in tropical‚ high salt alkaline waters where there is strong sunlight and a pollution free environment. The algae is harvested and spray dried and presents in a powder form for further processing. By volume Spirulina has unusually high concentrations of proteins‚ vitamins

Life as a Fish One of the most unique creatures are fish. As I am sitting here in my room‚ my fish are swimming about with not a care in the world. I wonder what it would feel like to be a fish. I’m swimming about and see eight other fish swim around me. The thermometer reads 72 degree Fahrenheit‚ but the cold water suits me just fine. There are white‚ black‚ and gray pebbles all over the bottom of the tank which collects the deserted food particles. I accidentally suck

window to enable them to photosynthesise as much as the beakers close to the light. The trend which was expected to be seen was that the light intensity is a limiting factor in photosynthesis. The greater the intensity of light‚ the more the plant/algae cells photosynthesises and so takes up more carbon dioxide as the rate is increased. The results do not show the general relationship between light intensity and

really do anything. Pretty much all sloths do is eat‚ sleep‚ and hang upside down. Sloths have some interesting things about them‚ one of them is their long nails or claws. Another interesting thing about sloths is that they have algae growing on their fur. The algae helps them survive because then they blend in with the leaves and grass. There are two kinds of sloths: 1) the two toed Sloth (like in its name it has two nails or claws)‚ and 2) the

domains of life? Why do some researchers believe that the Kingdom Protista should be split into more than one kingdom? In the early days of biology‚ all organisms were classified as either plants or animals. Single-celled eukaryotic organisms such as algae and Paramecium were assigned to one of the kingdoms according to whether they are photosynthetic or not. Fungi and prokaryotes were grouped with plants‚ because fungi are sedentary and prokaryotes have cell walls. A five-kingdom scheme was devised

turtles grow‚ their jaws become stronger‚ and when their jaws are strong‚ they switch to a strict vegetarian diet‚ eating algae and seagrass. Green sea turtles can get food and eat food by cutting and grinding seagrass and algae with their serrated jaws. Green sea turtles are the only sea turtles that are strictly vegetarian as adults. Just as Green Sea turtles get energy from algae and seagrass‚ sharks‚ mostly Tiger Sharks‚ get energy from sea
