Population Growth and Regulation
Yellowstone National Park is a region with diverse wildlife. Each animal in the ecosystem has a niche as a scavenger or predator. They are dependent on each other for survival because the predator/scavenger relationship in the ecosystem balances it so that no one animal is overpopulated in the park. At the top of the food chain are wolves and bears that prey on other animals such as bison and elk. Yellowstone ecosystem can support a number of organisms based on abiotic factors, such as temperature, soil composition, and quantity of water and light (Petersen, 2001). Given abiotic resources with no predators or diseases, populations can increase very rapidly including humans. Resources that lack or limit the population growth include predation and climate. The major source of energy for an organism in the ecosystem is sunlight which passes energy from one organism to another (Wagner, 2011).
Yellowstone has two major regulations that help maintain its ecosystem. The county has a United Zoning Code that sets limitations on building setbacks, parking of vehicles, land uses, and general property maintenance (Wagner, 2011). The other regulation set forth is the Decay Ordinance to maintain any salvaged materials or abandoned buildings seen by the public. These regulations are in place to keep the ecosystem safe from any...
