Biodiversity can be defined in several ways, but it generally refers to the number of species types in a particular ecosystem marine biodiversity therefore refers to the species richness and abundance in the world's oceans and seas. Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions among other factors, the diversity of all living things depends on temperature, precipitation, altitude, soils, geography and the presence of other species. Biodiversity biological diversity means the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part this includes diversity within species, between species and of ecosystems.

The cowardin system includes five major wetland types: marine, tidal, lacustrine, palustrine and riverine used by us army corps of engineers another common wetland classification system, used by the us army corps of engineers, was developed by brinson and is described in a hydrogeomorphic classification for wetlands . Biodiversity is defined as “the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part this includes diversity within species, between species and of ecosystems”.
Species biodiversity (refer to the number of different species living on earth) 18 million species has been discovered and described by scientists we think there may be between 5 and 100 million species. Marine species provide important ecosystem services such as the provision of food, medicines, and livelihoods they also support tourism and recreational activities around the world unfortunately, the resources of the sea have been over-harvested by humans, threatening marine biodiversity. The sambr is a synthesis of the state of knowledge about biodiversity in arctic marine ecosystems, detectable changes, and important gaps in our ability to assess state and trends in biodiversity across six focal ecosystem components (fecs): marine mammals, seabirds, fishes, benthos, plankton and sea ice biota.
