The Arctic Tundra ecosystem Arctic tundra is located in the northern hemisphere‚ encircling the North Pole and extending south to the coniferous forests of the taiga. The arctic is known for its cold‚ desert-like conditions. All of the plants are adapted to sweeping winds and disturbances of the soil. Plants are short and group together to resist the cold temperatures and are protected by the snow during the winter. They can carry out photosynthesis at low temperatures and low light intensities

they may even vanish from the ecosystem altogether. Similarly‚ over some time interval‚ other species within the community may become more abundant‚ or new species may even invade into the community from adjacent ecosystems. This observed change over time in what is living in a particular ecosystem is "ecological succession". why it occurs Every species has a set of environmental conditions under which it will grow and reproduce most optimally. In a given ecosystem‚ and under that ecosystem’s

on global warming‚ the fact remains that humans have an impact on the marine ecosystems through waste from chemicals and debris polluting this vast renewable resource. Based upon current scientific evidence‚ emissions of greenhouse gases from human activities are projected to cause significant global climate change during the 21st century. Such climate change will create novel challenges for coastal and marine ecosystems that are already stressed from human development‚ land-use change‚ environmental
