A class is a style of gameplay which determines the role of a character (defense, offense, or support), type of weapon (Twin swords, lance, axe, greatsword, disc, bow, staff, arcannon, powerfists, scythes, shuriken or scepter), armor (metal, leather or cloth) and skills available for a character of use.
Wetland functions and ecosystem benefits. Wetland functions are defined as the physical, chemical, and biological processes or attributes that are vital to the integrity of the wetland system. Because wetlands are often transition zones (ecotones) between terrestrial and deepwater aquatic systems, many processes have major implications for species. Since wetlands may provide food and habitat for many terrestrial and many aquatic species, wetland biodiversity is often higher than that of adjacent ecosystems.
Wetlands are habitats that fall somewhere on the environmental spectrum between land and water. Since wetlands lie at the interface of terrestrial and aquatic habitats, they possess a unique mixture of species, conditions, and interactions. As a result, wetlands are among our planet's most diverse and varied habitats.
