My Science Paragraphs
AMERICAN ELK
One of the animals that I have chosen for the first paragraph is the American Elk. I will talk about this animal and the eating habits of the animal. This animal is a secondary consumer so that mean that it eats producers. The elk eats varieties of greens, dried grass, forbs, sand and bark. It eats grasses such as native bluegrasses, rough fescue, Idaho fescue, prairie junegrass, needlegrasses, bluebunch and the primary foods in the summer and spring are slender and thickspike wheatgrasses along with sedges and early forbs. In the summer more forbs and woody browse are consumed by the elk and more dry grasses and browse are consumed in autumn. They do eat a lot but they do prefer grass. Although in the winter the American Elk eats woody vegetation and shrubs like serviceberry, willow, buds of red osier dogwood, antelope bitterbrush, snowberry, mountain mahogany, winterfat, aspen shoots, western juniper and sagebrush. This animals really take advantage of everything they find. However it seems that they eat a mixture of grasses, forbs and shrubs in the winter to make sure that they get the proper intake of nitrogen.
DOULBE CRESTED CORMORANT
The next animal that I will talk about is the Double Crested Cormorant. This animal is an bird but it is tertiary consumer. So that means that it will eat only other animals. Mostly the bird eats fish like: Walleye, Chinook Salmon, Coho Salmon, Lake Trout, Alewife, Gizzard Shad, Yellow Perch, Sculpins, Stickleback and many other fish that live near the surface of Lake Ontario and other bodies of water near the area. They eat the fish that are small (six inches). In a normal day the bird would get their food in shallow water (25 ft) within a few kilometres awa...

...FERS PARK
I think that Bluffers Park has good balance because it has the Dunkers Flow BANLANCING System. The facility consists of 5 cells built within a natural embayment and separated by pontoon-supported solid and curtains anchored to the bottom of the weights. I think that because the Dunkers flow system is a system for when the water levels rises and so it takes in the storm water and sewage overflow by passing it through a series of cells that with proper filters. The first cell is used for cleaning the sewage water, then it goes to the fourth cell and the retained water is pumped through a sedimentation cell and a wetland (cell 5) before it is released into the lake. So when the huge storm comes from all the factories the Dunkers Flow System should be able to balance the storm water. So I think that it has a good balance because of the Dunkers Flow System.
The climate in the Taiga make finding food and life in general difficult so in the winter animals migrate, hibernate or just cope with the harsh climate. Most of the main birds are non threatened like the bohemian waxwing, pine grosbeak, red throated loon and the hawk owl. The bohemian waxwing eats mostly fruit, and make thick nests in tall conifers unlike the hawk owl which nests in hollow tree stumps or abandoned nests and eats small mammals which it hunts in the day. The pine grosbeak nests in mostly conifers with diet of seeds and the red throated loon has a diet of fish because it spends most of its time on the water. Mammals include the ermine; a weasel like animal in which it...
The Bald Eagle is at the top of it’s food chain as a tertiary consumer. It
Darters are an important part of any stream ecosystem. They generally play the crucial role of secondary consumers, comprising most of their diet of soft-bodied animal...

In the last decade, from the Rockies to New England and the Deep South, rural and suburban areas have been beset by white-tailed deer gnawing shrubbery and crops, spreading disease and causing hundreds of thousands of auto wrecks. But the deer problem has proved even more profound, biologists say. Fast-multiplying herds are altering the ecology of forests, stripping them of native vegetation and eliminating niches for other wildlife. ' 'I don 't want to paint deer as Eastern devils, ' ' said Dr. McShea, a wildlife biologist associated with the National Zoo in Washington, ' 'but this is indicative of what happens when an ecosystem is out of whack. ' ' The damage is worse than anyone expected, he and other scientists say. Higher deer densities have affected growth, survival, and reproduction of many plant species which have aesthetic, economic or ecological value. In some cases, many species of trees have also been shown to have reduced growth as a result of high deer density (Environmental Benefits of Hunting, 1). Deer prefer certain plant species over others and frequently feed on economically valuable tree species. For example, they prefer oak and sugar maple seedlings, as well as acorns, over less palatable species like American Beech and striped maple. Thus, less marketable species are more likely to survive to maturity,

In many areas, the deer have adapted to eat primarily agricultural crops (crops grown by humans). In many parts of the country, a deer’s diet may consist of up to 50% farm grown corn. Obviously the deer eat some native foods, such as some trees and bushes, particularly buck brush and rose, but along with small amounts of dogwood, chokecherry, plum, red cedar, pine, and many other species of plants. Forbs, particularly sunflowers, are important, however grasses and sedges are used only briefly in spring and fall.
The way storm water ponds work, they collect runoff, of course, it then slows the water. This is done so that it will hold long enough to allow gravity to pull out sediments from the water and allows sunlight and biochemical systems
According to William Cohn, a conservation specialist, deer are “voracious eaters.” He also claims that if an area becomes too overpopulated with for example, deer, there will be a scarcity of food and lead to starvation.
“The animals are reducing the number of trees and seedlings and affecting which species will survive, forestry experts say” (NBC news). A wildlife professor estimated that deer cause at least $750 million in damage to the timber industry. This becomes a big impact on the economy. “We view it as problem of our own making,” said Laura Simon, field director of urban wildlife and sanctuaries program for the Humane Society of the United States. “We have created an ideal landscape for deer.” (NBC news). Deer are said to eat anything and everything, this is especially proven when farms have their crops
Remember when it was published that Pluto is no longer considered as a planet? I remember that our physics teacher was really angry about the fact that in space agency discarded the fact that was known and generally accepted by the general public. In my essay I will discuss how the “old” knowledge was affected when there were new aspects of particular knowledge discovered. I will focus on two areas of knowledge: The natural sciences and the arts and I will ask myself: To what extend can new knowledge contributes to abundance of old, generally recognised facts?
As urbanization continues to expand amphibian population are on a global decline. In many rural areas, the only wetland available for aquatic reproduction is artificial ponds. While some species are able to persist in such an environment the majority of amphibians are negatively affected. The introduction of non-native species along with habitat degradation affects the successful reproduction of these native amphibians. Therefore, an understanding of the relationship between these species and their habitat is essential for conservation. This research sets out to determine conservation priorities for pond breeding amphibians in the hopes of preserving their existing populations.
Evolution is defined as the change of hereditary characteristics of populations over generations (Caroll, 2009). The environment is continually changing therefore organisms have to change in order to stand the changes in environment so they can survive and reproduce (Caroll, 2009). Regular change in genetic material of organisms over generations can lead to the development of new species that are more adapted to the environment (Caroll, 2009). It is said that failure to evolve may lead to extinction of a species (Caroll, 2009).
As humans our population is increasing at a very rapid pace. Human interference with the natural wildlife is skyrocketing the rate of extinction for the animals that we coexist with. As more and more humans are born the more territory is required in order to live a comfortable life, but it seems that we are not aware of how our expansions throughout the world is affecting the lives of the native species. We jeopardize the lives of these animals when we recklessly flatten the surrounding land and drive the living animals out of their natural habitats. When we feel the need to acquire more territory in order to create a suitable place to live on, we destroy the already occupied land of the native species thus driving the rate of extinction to increase. The occupation of the animals’ native soil forces the animals to leave the area in hopes of adapting to another piece of land. For some this adaptation is simply impossible and the species begin to die off. In an article on Treehugger.com the author states, “Thanks to human development and expansion, species are now going extinct exponentially faster than ever before- they’re dying out at the frightening speed of one thousand times their natural rate (Merchant 1). As we are busting around making these “developments”, we pollute the natural landscape with petroleum products, pesticides, and other chemicals. When this happens we endanger the living species and speed up the process of extinction because of our interference with the local wildlife.
