The deep sea contains up to 95% of the space occupied by living organisms. [40] Combined with the sea floor (or benthic zone), these two areas have yet to be fully explored and have their organisms documented. [40] [41]
Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. [1] The biome is dominated by grass and/or shrubs located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes. Tropical grasslands are mainly found between 5 degrees and 20 degrees in both ...
