The energy flow among organisms of a food chain Assignment

The energy flow among organisms of a food chain - Assignment Example The red squirrel is also well adapted. Firstly, the skin is adapted well for camouflage and protection from the predators. Secondly, their eyes are sensitive to such an extent that they have clear vision in the night and thus can hunt for food. The wood land vole adapts to the changing climate of the deciduous forest via their ability to hibernate. The rodent builds a furrow and enters into a state of dormancy during harsh climates and decreases its metabolic rate and finally coming out of the hibernacula at the time of spring. The weasels are mainly adapted in the ecosystem through their ability change fur color via molting. During molting the weasel sheds the existing layer of fur and slowly alters it to a color that fits the environment. This adaptation makes these organisms successful predators particularly with their ability to blend into the pure white snow Almost all deciduous forests have been a subject to human impact. Due to changes in the atmosphere chemistry, indirect elevation of CO2 has shifted the forest productivity as well as the composition of the forest species has been shifted. A greater factor affecting the population of animal species in the ecosystem is the raised levels of nitrogen deposition. This could have an impact on the specie population within the habitat, litter quality and nutrient mass cycling rates. The major hazard caused by human population is the deforestation. This affects the climate of the ecosystem and is observed to cause changes in the evaporation rate as well as the precipitation rate. Â  In those areas where evaporation increases more than precipitation, soil will tend to become drier, the lake levels will drop, and the rivers will carry less water. Other threats involve the air pollution, global warming and human development. Regarding the population growth of the ecosystem is concerned; the bi otic potential can produce an
