Niche of Assigned OrganismList common name and scientific name<br />Minks live in wilderness and rural areas close to rivers , streams, and other bodies of water.<br />Minks are carnivores and hunt on land and in water. Crayfish, minnows, and frogs are some of its food sources in water. Some of its on land prey include muskrats, mice, rabbits, and snakes. Occasionally otters consume minks but mainly only decomposers rely on minks.<br />Mink mate from April to May and has 5 to 6 young. The mother cares for its young until they are mature. Then they go out on their own. It hunts most of the day near the water. It looks for prey and dives into the water to capture the prey.<br />
Food Chain of Assigned Organism<br />This is a possible food chain for the mink. It is a tertiary consumer so it is at the end of the chain.<br />Primary Consumer<br />Omnivore<br />Producer<br />Autotroph<br />Secondary Consumer<br />Carnivore<br />Tertiary Consumer<br />Carnivore<br />
Food Web of Assigned Organism<br />This is a possible food web for the mink. It is a tertiary consumer so nothing eats it.<br />Carnivore<br />Carnivore<br />Herbivore<br />Omnivore<br />Producer<br />Omnivore<br />Producer<br />Herbivore<br />Herbivore<br />Producer<br />Carnivore<br />
Stream Quality Data & Analysis<br />The stream conditions are very good because it is dominated by class one organisms which are intolerant to pollution.<br />The amount affects the stream quality because class 1 organisms are intolerant to pollution while class 3 organisms are tolerant and class 2 are somewhat tolerant. A healthy stream would have more class 1or 2 organisms than class 3.<br />This stream would positively affect the mink because it would have plenty of healthy prey to hunt.<br />
Water Testing Data & Analysis<br />The levels of each of the nutrients are very important to determining the diversity of life that can live in the ecosystem.<br />The ideal level of nitrates and phosphates are zero. The ideal level of Ph is 6.5 to 7.5. The ideal range for dissolved oxygen is 10 or above.<br />If the mink lived close to the stream it would survive easily because it would have a good food source. It would not be able to survive long in the other areas because those water sources would not be able to support the mink’s prey.<br />Also, the temperature and turbidity have to be at a certain level because if it is to warm or cloudy it would not have any prey or could not find them.<br />
Positive and Negative Factors<br /><ul><li>The stream waters would affect the mink positively because it would have a healthy food source and clean water. The marsh and mine waters would negatively affect the mink because the prey it hunts would not be able to survive in them.
Abandoned mine drainage and agricultural runoff are two common negative factors on the riparian zone. One positive factors would be passive treatment of AMD by humans. The riparian zone should be preserved by treating AMD water strictly monitoring pollution laws. AMD and agricultural runoff would negatively affect the mink because the organisms it relies on for food would not be able to survive in the polluted laws.</li></li></ul><li>Conclusion<br /><ul><li> I learned that abandoned mine drainage is a big problem to local streams.
I thought it was interesting that they can treat AMD with settling ponds.
I might want to research water pollution treatments further.</li></li></ul><li>Work Cited<br />Mink on World Book Online, 2010<br />Mustela Vision (American Mink) on Rodents and Others at www.the-piedpiper.cu.uk/th1i.htm<br />AP images on power school<br />
