Within any community some species may become less abundant over some time interval‚ or they may even vanish from the ecosystem altogether. Similarly‚ over some time interval‚ other species within the community may become more abundant‚ or new species may even invade into the community from adjacent ecosystems.

Introduction An ecosystem‚ according to Oxford Dictionary is “A biological community of interacting organisms and their physical environment” (Oxford University Press‚ 2017). An ecosystem can range in size from a large reef to a tree stump (University of Michigan‚ 2017)‚ the range of ecosystems is staggering. This report will investigate ecosystems and the connections within them‚ using Kakadu National Park (Northern Territory‚ Australia) as a case study. This report will also cover the impacts that

The Everglades ecosystems contain a diverse environment that stretches from the middle of the Florida peninsula to Florida Bay. The Everglades consists of endless marshes‚ towering palms‚ alligator holes‚ dense mangroves‚ and tropical fauna. Fire‚ water quality‚ and geology are just a few of the natural factors that help shape the development of the Everglades‚ with frequent flooding in the wet season and droughts in the dry season (Everglades‚ 2013). Although many natural occurrences take place
