Rachel Broniec Blue-Green Algae Lake Erie Cat Fish Scientific Name: Cyanobacteria Cyanobacteria use phycocyanin to retain light so that they can perform photosynthesis. They are photosynthetic and can obtain their own food. These organisms can convert inert atmospheric nitrogen and change it into its organic form. Four ways this organism has adapted too its environment are: Usually this organism lives on greenhouse glass, drains, and sinks. It had too adapt too living in water by maybe living on passing boats or on other organisms. Living on greenhouse glass and then going too a lake environment means they would have to live close too the surface too get the light they need too perform photosynthesis. This organism would also have too adapt too having many more organisms feed off of it now that it is in a heavily populated environment such as a lake. Green Algae Scientific Name: Pediastrum Boryanum Green Algae contains two types of chlorophyll allowing it to conduct the process of photosynthesis for food.

Green algae lives in small colonies of 8-32 Pediastrum Boryanum. Four ways that diatoms adapt too their habitat are: Four ways this organism has adapted too its environment are: Algae grow faster in warmer water, and therefore usually live in warmer waters. Pediastrum Boryanum have had to learn to continue to reproduce in the cold winters of Lake Erie. Many of the other organisms in Lake Erie feed on Pediastrum Boryanum so they have had to adapt to trying to avoid being eaten which they do by grouping together their colony with other colonies which provides cover from some of their predators. http://www.fcps.edu/islandcreekes/ecology/green_algae.htm Some diatoms live on other organisms such as plants, turtles, and crustaceans. However these organisms listed are not usually found in lakes. This means diatoms would have too find newer organisms too live on. They may just float freely. Also if they could not obtain the light needed too make their food then they would have too adapt to eating off of other organisms. http://www.ucmp.berkeley.edu/chromista/diatoms/diatomlh.html To adapt to living in deeper waters they form a layer of slime to help them float in water and at the surface which aids in photosynthesis by allowing them to be closer to where they absorb sunlight. Because diatoms use sunlight too make their food through photosynthesis, that means that if they don't find sunlight in their new environment because of the place that the organism they are on lives then they wont make food. They form into the smaller colonies because they are too small to survive on their own and it is more beneficial to their growth to stay in colonies but it is because of how fast they grow that they will never live in colonies consisting of more than 32 cells. Flagellates Flagellates are single-celled protists with one or more flagella which are whip-like structures used for movement. They can be autotrophic or heterotrophic. Because diatoms are plentiful in freshwater and marine ecosystems, that means that they can feed a large amount of organisms that may have not been fed as much before, which means that diatoms would have too get used too being used a lot. When diatoms are put into a new environment they may have too adapt by eating other organisms than making their own food. Northern Pike Esox lucius Scientific Name: Northern pike have a flat and wide nose and range from 2 too 7 pounds and are usually 15 too 3 inches long. The pikes usually live in weedy areas, estuaries, and shoals in the spring and summer. In the winter however, they go too deeper water. Pike feed on crayfish, fish, frogs, and mice. They will eat anything that comes in their territory and are omnivorous carnivores. Four ways the northern pike could adapt too its environment are: Because the northern pike like too live in vegetation too easily hide from their prey, this fish would have too live in shallow water where there is vegetation. If the winter comes and this organism needs too go to deeper water, they would have too leave behind all their prey on the shallow end and hope for some prey in the deeper water. When the season changes from winter too spring in the following season, then the northern pike would have too find its way up back too its area and adapt to the change in temperature. If the northern pike could not catch any food during the time when the seasons change because other organisms left that area before, then the organism would have too learn too eat the vegetation it lives in. http://www.justsportfishing.com/northern_pike.html Black Crappie Pomoxis nigromaculatus Scientific Name: The Black crappie is a native too western Lake Erie and prefers clear water with little too no vegetation. Black crappie live relatively in lakes, ponds, streams, and reservoirs. Black crappie breed in may and June and grow up too 16 inches long and can weigh up too five pounds. Black crappies eat: Young: zooplankton. Adult: small fish, insects, crayfish, tadpoles Four ways this organism can adapt too its environment are: Because the black crappie like clear water with little vegetation, they would probably live on the surface or close too the surface. If the black crappie ran out of organisms too eat they may need too adapt too eating plant life which means they would have to go too deeper areas with more vegetation. As a young crappie if there was not enough zooplankton, then the young crappies may have too get used too eating plants if the bigger food cant fit in their mouths If the crappie cannot find a good enough spot too live in because there is too much vegetation, it may need too adapt too living in such an environment. Four ways this organism has adapted too its environment are: Threats to this Biome: One of the threats too this Biome and the organisms in it is the conversion of land into unnatural urban development. Some of the changes of land resulted in intensification of agriculture, and construction of shore lines. These changes have affected the ocean very badly and caused the water too drop in quality and quantity. This making the life of organisms in this Biome, unsustainable. It is proven that over 90% of the land is changed for agricultural and urban use. The type of living that is in Lake Erie, is a clean and sustainable environment. However, if people continue too mess up the balance in this biosphere then, the organisms will have too adapt too the type of water they are living in. This threat would not only change the way these inhabitants live, but alter the culture and standard of living forever. Flagellates are used to having easy access to large amounts of food but with such a large amount of consumers in Lake Erie they have had to adapt to not having as much food readily available to them at all times. http://www.environmentalleverage.com/Flagellates.htm Scientific Name: Dinoflagellates They are used to feeding with small groups of flagellates and because of Lake Erie's massive size, they have had to adapt to feeding in larger groups. They are used to living in sludge at the bottom of shallow bodies of water but because they rely mainly on photosynthesis for food they had to adapt to living closer to the top of Lake Erie. http://tolweb.org/notes/?note_id=50 Using their flagella for movement they have adapted to the massive size of Lake Erie. White Perch Scientific Name: Morone Americana This fish is not native to Lake Erie in fact it has migrated from the waters from Maine to South Carolina Four ways this organism has adapted too its environment are: It's main food sources are fish eggs and minnows which may also be eaten by other animals so it has had to learn to hunt for its food with competitors. This fish is smaller than some other predators such as the Pike so it has had to learn survival skills to not get eaten. These fish also have had to learn to hide from other unlikely predators such as birds that fly over the water and scoop them up for a meal These fish are also used in sport fishing and if caught must be killed so they really have had to adapt to a life of pure survival. http://www.in.gov/dnr/files/WHITE_PERCH.pdf Scientific Name:
Flathead Catfish Recognizable by their flat head. They can grow to be very large; the largest record was 124lbs. Four ways this organism has adapted too its environment are: These fish are very large and require a lot of room to live because of the large amount of animals and different species in Lake Erie they have had to adapt to less personal living space. Flathead's are fished for very frequently and have had to adapt to avoiding fishermen. Catfish are prey for other larger catfish so they constantly have to get used to being on guard for other catfish. Catfish usually live in moving bodies of water like rivers and living in Lake Erie that is much more still they have had to adapt to all of the changes that come with living in stiller waters like prey and cover. http://www.pserie.psu.edu/seagrant/ais/watershed/catfish.htm Pollution Threats to this Biome: Both point and non-point sources of pollution are involved in the polluting of Lake Erie.
Toxic chemicals coming from the Detroit River are poisoning drinking water and killing off fish and other wildlife which in turn effects the food source of humans. The Lake is usually a peaceful place that attracts many fishermen and tourists. It is home to many species of wildlife that will continue to be negatively effected by this pollution. If the lake continues to be polluted as such it will in time become unsustainable for any kind of life which would hugely effect not only the species that live there but humans as well.
