Nikki Dedic Student ID #22042666 Exam # 25085500 Ecology Essay 1. Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. Eutrophication is a naturally occurring‚ slow‚ and inevitable process. However‚ when it is accelerated by human activity and water pollution called cultural eutrophication‚ it can lead to the premature aging and death of a body of water. Cultural eutrophication occurs when humans speed

Although I was only in third grade‚ the destruction of the environment affected me more deeply than most of my fellow classmates and continues to do so today. I wish to embark on an educational journey to beautiful Montverde‚ Costa Rica for the Tropical Ecology and Conservation program in the Spring of 2009. In order to take this step in my educational career‚ I am applying for financial aid through the John E. Bowman Travel Grants‚ CIEE International Study Programs Scholarships‚ and the Jennifer Ritzmann

By the same token‚ the Mexican wolf was subsequently thrown into endangerment due to improper conservation evaluations and lack of ecological research. This goes to show that ecology has come a long way since the nineteenth century‚ and has ultimately worked its way toward better scientific evaluations and stricter conservation

Introduction Ecosystem is similar to a community. It consists of species‚ living organisms and the abiotic factors‚ their habitat. Living organisms includes animals‚ plants‚ insects‚ micro-organisms. For their habitat‚ they are the non-living nature which are soil‚ sunlight‚ water‚ precipitation. There are two types of ecosystem. Terrestrial ecosystem which is on the land and aquatic ecosystem which is under the water. Over-breeding is the increase of offspring of a species to a excessive number

many elephants or fires then the number of trees in the Serengeti will decrease but if there is not enough of them then again the ecosystem will change as they control the establishment of trees. Fire is monitored and controlled through the Park Ecology Department who ensure that there is enough fire but that they do not get out of hand. The Serengeti is also managed by having a top-down approach to management where the park authorities co-operate with the Masai (indigenous people in the Serengeti)
