Are water samples different in different aquatic ecosystems?
There are some oceanic ecosystems that have lots of nutrients for plant growth. The Arctic Ocean, Antarctic and the Bering Sea are very rich ocean ecosystems. These oceanic ecosystems are very different than the seas around Hawaii and the South pacific. There is little plant life in the waters around Hawaii, as there are not a lot of nutrients. The ice is what makes aquatic ecosystems different. In the Arctic and Bering the ice comes in winter and mostly disappears in summer. This ice regulates animal life, and eventually through the food pyramid affects large mammals like the polar bear. The ice also provides resting place. Are the ocean ecosystems being affected by global climate change? The Ice in the Arctic Ocean is melting faster than scientific models predicted. Professionals in the field are predicting that within the next 20 years that there will be no summer ice in the arctic. There will always be ice in the winter, but now there are major concerns about summer ice. Scientists
