Ppt Adaptations In The Marine Biome Powerpoint Presentation Free The document discusses various adaptations that allow marine organisms to survive in the ocean environment. it notes that the ocean provides a more stable environment than land, but organisms are less able to withstand changes. it describes several physical adaptations for buoyancy control and movement through water, including streamlining, oil. Introduction to the marine environment. ocean planet 72% of surface is water 70% seawater 2.0% fresh – 1.51% ice, 0.49% liquid, .00007 vapor life present 10x longer than on land 3 d habitat 98% of biosphere. origin of water . 4.5 bya during planet formation. download presentation. box model. atmosphere exchange. decomposition. deep water influx. Adaptation is an evolutionary process whereby an organism becomes increasingly well suited to living in a particular habitat. it is not a quick process! natural selection over many generations results in helpful traits becoming more common in a population. this occurs because individuals with these traits are better adapted to the environment. 10 adaptations to marine environment. camouflage through colour patterns countershading – dark on top, light on bottom disruptive colouration – large bold patterns, contrasting colours make animal blend into background. 11 camouflage and countershading. 12 water pressure many marine organisms – no inner air pockets.

Marine life has developed many adaptations to the variations in temperature. many marine mammals have blubber for insulation from the cold, and some fish have an antifreeze like substance in their blood to keep it flowing. it is interesting to study the dramatically different adaptations in marine life on a vertical scale in the water. Marine organisms have adapted to the great diversity of habitats and distinctive environmental conditions in the marine environment. adaptations are many and varied but they are generally grouped into 3 main categories: structural, physiological and behavioural. structural adaptations. structural (or morphological) adaptations are the physical.
