related. If anything change occurs in one part of an environment ‚ then the whole environment will be affected. For example if the population of plankton in a marine area goes extinct so will its consumers the zooplankton die and so will the other fish that eat the zoo plankton such as crustaceans . Marine life could not exist without plankton . Scientist often times use ecological models to help them represent parts of an ecosystem and to help them understand environmental interactions

Growing our own Garbage Patch Jessica R. Willard City University Growing our Garbage Patch Planet Earth is comprised of approximately 75% water. 96% of that 75% is all ocean water. The ocean is actually one very large body of water that is divided up into different smaller oceans. The large body of water is called “The World Ocean” and the individual smaller oceans are “The Pacific Ocean”‚ “The Indian Ocean”‚” The Arctic Ocean”‚ and” The Atlantic Ocean.” In the past‚ oceans have been viewed

Marine debris‚ commonly known as marine litter‚ is man-made waste that is deliberately or accidently released into oceans‚ lakes‚ seas or any other type of waterway. 6.4 million Tonnes of garbage are found in the world’s oceans every year and it just keeps increasing. 90% of this garbage is found to be plastic. Marine debris comes in many different forms. One form is ghost nets‚ these are fishing nets that fish and other creatures get caught in. The ghost nets restrict movement which means that

depletion of a species of fish to the level of extinction. This may not seem like such a major problem. However if a type of fish species was to become extinct it would result in a domino effect. The producers‚ which are photosynthetic organisms like plankton‚ have a key role in the food chain as they the base and all of the energy for the system comes from them. These producers are then eaten by the consumers like small fish. These small fish aren’t always the fish which are hunted by humans but they

When the tide was high‚ she would be standing on the inlet bridge with her plankton net. [6] I have great respect for my mother. I learned

But those are not the sponges I am talking about. -Sponges are simple‚ multicellular but beautiful filter-feeding animals. They are from the phylum porifera and are invertebrates that live in the bottom of the ocean and cannot move from their surface. -Sponges are also ancient creatures. 3

Acidification in our Oceans Oceanography April 2‚ 2013 What is Ocean Acidification? “Ocean Acidification‚ is the worldwide reduction in the pH of seawater as a consequence of the absorption of large amounts of carbon dioxide (CO2) by the oceans.” (Britannica). Ocean acidification is largely the result of loading Earth’s atmosphere with large quantities of CO2‚ produced by vehicles and industrial and agricultural processes. Since the beginning of the Industrial Revolution about

We see stars on the television or in movies. We see stars amongst dark starry nights. We have all seen the obvious types of stars but have we ever stopped to think about the star in the ocean? Echinoderms or starfish also known as the “stars of the sea” are very interesting marine animals that breathe out of their pores‚ and are able to regenerate their own arms. I don’t know about you but that is the most interesting thing I have ever heard. To begin with‚ the starfish started out about half

June 8‚ 2009 -- Giant jellyfish like this one are taking over parts of the world’s oceans as overfishing and other human activities open windows of opportunity for them to prosper‚ say researchers. In this photo‚ a diver is attaching a sensor to track a monster Echizen jellyfish‚ which has a body almost 5 feet across‚ off the coast of northern Japan. Jellyfish are normally kept in check by fish‚ which eat small jellyfish and compete for jellyfish food such as zooplankton‚ researchers said. But

Cyanobacteria including those that form stromatolites There have been many technological advances that have lead to a greater understanding to the world that we live in‚ especially over the past 50-75 years. Developments in technology such as the light microscope and the transmission electron microscope particularly have made research in the field of bacteria and in this case Cyanobacteria much easier‚ removing barriers and creating a situation where there are barley any limits.
