Ecology is the scientific study of interactions among organisms and their environment‚ such as the interactions organisms have with each other and with their abiotic environment. Topics of interest to ecologists include the diversity‚ distribution‚ amount (biomass)‚ number (population) of organisms‚ as well as competition between them within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms‚ thecommunities they make up‚ and the non-living components

For example‚ the weather becomes hot and dry in wetland areas‚ the animals and plants in those areas find it hard to survive. As the result‚ the places will be vanished. Therefore‚ the governments should restrain the tourists from natural areas for the benefits of local species. The second reason for
