decided to research and write about is called “Rusty Waters”, written by Rob Raiswell. This paper discusses that the Greenland Ice Sheet plays an important role in how the North Atlantic Ocean receives iron and how this iron can be utilized by phytoplankton. The scientists came up with this idea through a series of tests, observations and critical thinking. Using different samples of meltwater from glaciers in the Greenland ice sheet, they determined the amount of iron available for plankton. Next

The Red Snapper is also known as Lutjanus campechanus, they are pink to a red color (Louisiana Fisheries). They are commonly known as the North American Red Snapper, Snapper, Genuine Red Snapper. Their color starts to fade off under their bellies (Louisiana Fisheries). Some key characteristics are their red eyes, and their anal fin pointed than rounded. (Louisiana Fisheries). They can be found in the Gulf of Mexico and the Western Gulf (Louisiana). They can weight about anywhere ranging from 10-50

Describe how human impacts are causing many species to become endangered or go extinct. Humans do a lot of bad things, that cause many species to go extinct or become endangered. One of the biggest problems is human predation. Humans do a lot of harm by hunting. They erased the megafauna mammals of the last Ice Age, decreased the population of whales and other marine mammals, and wiped out the Dodo Bird and the Passenger Pigeon. Another problem is that animals lose their habitat. Mostly, animals

benefits and advantages of phytoplankton over larger plants on land and within the ocean is that, according to the same National Geographic article previously stated, they are so small in size that millions can fit into a single drop of water. This means that phytoplankton have the ability to supply a greater amount of oxygen while occupying smaller square footage when compared to other plants. In fact, according to Dr. Sylvia A. Earle of National Geographic, phytoplankton account for such a large

important for oceanographer to study phytoplankton? Plankton is found all over the planet, these are organisms that live in the oceans. They are very small and they can’t swim very well against current. Many plankton organisms are either a plant or animal and planktons are consider the most important organism of the ocean. One of the most important categories of plankton are phytoplankton which are small plants that are only visible by using a microscope. Phytoplankton plays an important role in the ocean;

3. GROWTH AND CELL DIVISION OF PHYTOPLANKTON Phytoplanktons have diversity and are of both the types prokaryotic and eukaryotic. Cell division is the vital process for regeneration. Prokaryotic forms of phytoplankton which comes under domain bacteria divide by basic process of cell division like binary fission. Eukaryotic phytolanktons which comes under domain eukarya are divide by the process of mitosis. For the growth of phytoplankton twenty nutrients are required. Many elements like nitrogen

Alexandra Edwards Microbial Ecology SoFEX Experiment Phytoplankton are microscopic photosynthetic organisms that inhabit the surface waters of the oceans. Major nutrients such as nitrates and phosphates are required for the growth and exist in abundant supply, yet the production of chlorophyll in particular areas of the oceans by phytoplankton is lower then would be expected (Watson, 2012). Investigations into these high nutrient, low chlorophyll (HNLC) regions, such as the Southern Ocean, have

abundance of phytoplankton in the pond depends on the abundance of an abiotic resource such as nitrogen. - Phytoplankton are the producers in the pond. Species of organisms in ecosystems have their own carrying capacity relative to other species, and carrying capacities are determined by particular abiotic and biotic resources in an ecosystem. An increase in nitrogen levels in the pond (e.g. from fertilizers) will result in a dramatic increase in phytoplankton levels, but once phytoplankton population

This had a huge effect on the planktons. Zooplanktons the eat phytoplankton. If there isn’t much phytoplankton for the zooplankton to eat, there numbers will decrease. The article “ The Short‐Term Impact of the Zebra Mussel Invasion,” “phytoplankton fell by 80 percent. Zooplankton (which eat phytoplankton) declined by half. And the smallest zooplankton (called micro‐zooplankton), fell by about 90 percent.” Finally, dissolved oxygen

early summer. According to the animation, the North Atlantic Ocean is most productive during March and April. This is most likely due to phytoplankton beginning to become exposed to more sunlight, which initiates heightened photosynthetic activity. The more phytoplankton there are in an area, the more productive the area is because there are more phytoplankton for consumers to feed off of. 3.) Productivity

‘ultra-food’ is known as phytoplankton. Phytoplankton basically refers to numerous aquatic microscopic organisms that utilize light and dissolved carbon dioxide to produce their energy and nutritional requirements. Scientists say a small dosage of this item contains a large amount of the vitamins, minerals and nutrients needed by the body to function optimally. Although this revitalizing item has been known for many years, the difficulty in sourcing fresh phytoplankton had prevented its widespread

some which are zooplanktonic, such as copepods (Anderson). Focusing on the holoplanktonic phytoplankters, diatoms are known for being “the most productive photosynthetic [plankton] organisms” (Garrison and Ellis 400), and are a prevalent form of phytoplankton. Due to both of these factors, diatoms provide a notable amount of oxygen consumed by other marine animals and even Earth’s atmosphere; this is generally what determines them as part of the first stage of a food web. Genevieve Anderson, a Santa

phosphorous and nitrogen, in some places of the world these nutrients are present in huge quantities because of the workforce of the man, this causes a massive production of this proptosis. Phytoplankton are eaten by small fishes but in these cases is difficult that the depredators can not be able to eat all the phytoplankton, some organisms are eaten and some others just die, both generating trash, the waste effects on the production of oxygen in water causing the problem known as hypoxia. Hypoxia is also

There are some pretty bad things going on in the Hudson river. Have you ever seen a zebra mussel. Or even let alone heard of these kinds of creatures. Well let me tell you exactly what is going on in the Hudson river. It’s also very sad as well because entire ecosystem is going down with the recent crazy population of the mussels. Zebra mussels started to show up in the Hudson river in may 1991. Scientists estimated there size in numbers and it turned out to be a whopping 500 billion. That is a

river and became an invasive species and might be a worldwide problem. In the Hudson river the present of phytoplankton has drop by 80 percent. Scientists believe that this is because the phytoplankton is being eaten by the Zebra mussel. This causes the zooplankton, who eat phytoplankton to die. This has made zooplankton present to go down by half. The smallest species of phytoplankton have died down by 90 present. Most other mussel in the Hudson have gone down for billions to almost none. Ever

A question that many wonder about is why is phytoplankton important? Plankton is revealed by ocean color and help show scientists where ocean currents provide nutrients for plant growth. They also help show where pollutants are poisoning the ocean preventing plant growth and where changes in the climate of the ocean are occurring. Plankton is also the foundation of the oceans food chain. As phytoplankton begin to grow and multiply, small fish eat them, then the larger animals begin to eat those smaller

Introduction Oxygen is known for being essential for human respiration, but it is critical for all life. This includes marine life as well. Oxygen is delivered into marine ecosystems when it is dissolved in the water. Dissolved oxygen enters the ocean from the atmosphere and from photosynthesis. Photosynthesis is the process used by organisms to create their own food, by using water and carbon dioxide. Photosynthesis varies with solar radiation levels. Higher levels of photosynthesis are recorded

strong focus on the addition of Phosphorous and added toxins because both are key elements in growth in lakes. The Virtual lake includes these five simulated species; green algae, cyanobacteria, bosmina, daphnia, and trout. There are two types of phytoplankton in the lake model, green algae and cyanobacteria. Green algae are a very diverse group that are photosynthetic, aquatic, plant like organisms that have a very simple reproductive structure. Green algae growth is a healthy and natural part of a

characterized by lots of rain, high humidity, and low pressure in California/Peru and arid temperatures and high pressure in Asia. The water off the coast of Peru can be up to 10 degrees warmer, and since there is less upwelling there is less phytoplankton in the water.
