INTRODUCTION Background of the Study Seagrasses are the marine flowering plants. They are the only angiosperms that successfully grow in tidal and subtidal marine environment. Seagrasses belong to the families‚ Hydrocharitaceae and Potamogetonaceae and they are in no way related to the terrestrial grasses of Poaceae. There are 13 genera and 58 species available all over the world. Of these‚ six genera (Amphibolis‚ Heterozostera‚ Phyllospadix‚ Posidonia‚ Pseudalthenia and Zostera) are mostly restricted

affected by ozone depletion. The life cycles of plants will change‚ disrupting the food chain. Effects on animals will also be severe‚ and are very difficult to foresee. Oceans will be hit hard as well. The most basic microscopic organisms such as plankton may not be able to survive. If that happened‚ it would mean that all

The idea of an ocean’s surface with a red hue may seem like a very amazing phenomena but in fact it’s quite the opposite. Red tides are becoming more and more harmful to not just the sea life it’s consumes but to us humans as well. When we use pesticides and other man made chemicals‚ we are washing them away without a care of what happens next. In doing so‚ they are eventually ending up back into our oceans and cause these harmful algal blooms‚ known as Red Tide. Most of these algal blooms are toxic

radiations can cause damage to human health‚ ecosystems and to the global climate. They can cause skin cancers and catatracts of the eye‚ as well as decrease the immune reactions‚ making humans vulnerable to infections‚ diseases. They can also kill plankton‚ thereby destroying the marine ecosystems. Many plants are also unable to tolerate an increase of whole ecosystems‚ threat to the food security of the world‚ are some of the other effects. Ozone depletion can also result in a stratospheric cooling

Bahamas‚ Florida‚ and Bonaire. Snails feed off these sponge but are no threat to them compared to humans. The dense populations of these sponges have gone down because of toxic dumps and the oil spill. Stove Pipe Sponges are filter feeders and eat plankton or suspended detritus as it passes them. They reproduce sexually and asexually. When they release sperm‚ it floats in the oceans water and eventually lands somewhere. Wherever it lands‚ it begins to reproduce cells and grow. They can take up to hundreds

eahSeahorses are truly unique‚ and not just because of their unusual equine shape. Unlike most other fish‚ they are monogamous and mate for life. Rarer still‚ they are among the only animal species on Earth in which the male bears the unborn young. Seahorses have no teeth and no stomach. Food passes through their digestive systems so quickly‚ they must eat almost constantly to stay alive. Found in shallow tropical and temperate waters throughout the world‚ these upright-swimming relatives of the

Units (JTUs). Background Turbidity is a measurement of how cloudy water appears. Technically‚ it is a measure of how much light passes through water‚ and it is caused by suspended solid particles that scatter light. These particles may be microscopic plankton‚ stirred up sediment or organic materials‚ eroded soil‚ clay‚ silt‚ sand‚ industrial waste‚ or sewage. Bottom sediment may be stirred up by such actions as waves or currents‚ bottom-feeding fish‚ people swimming‚ or wading‚ or storm runoff. Clear

SpongeBottom and Adam Sandler In our adaptation of Shakespeare’s play A Midsummer Night’s Dream‚ the character Nick Bottom or Bottom the Weaver is played by our character Spongebottom in Bikini Bottom Battle. Spongebottom can be identified with the actor Adam Sandler due to Sandler’s habit to play as characters who are not quite normal and are faced with. Sandler has had experience playing this type of character in movies such as The Waterboy and Billy Madison which is why he would be a great

some types of graptolites floated on the surface of the oceans while others lived in deeper water over the self-edge and upper slope and some lived at great depths. Graptolites lived at all levels of the water column and their main food source was plankton. However‚ we don’t know for sure how graptolites lived because there is not enough information about them to link them to any living organisms. 3. 3-3A. a) Genus: Monograptus b) Order: Graptoloidea 3-3B. a) Genus: Tetragraptus
