Two different populations cannot occupy the same niche at the same time, however.



So the processes of competition, predation, cooperation, and symbiosis occur . Humans let the unique ability to modify existing ecosystems, which can greatly upset their natural nutrient cycles. (Audesirk & Byers, 2011). When an ecosystems natural heftiness flow has been disrupted by eliminating food sources for other animal populations even the human population can eventually flummox harm.(ibid). Humans clear forests or grasslands to grow crops, later, they build houses on what was once farmland; and finally, they convert small towns into cities. (ibid) Coastal ecosystems are most vulnerable.
