Re: Ocean green machine
Friday, July 30, 2010
We learn lots of things from the video. We learn that the ocean is full of phytoplankton. Phytoplankton is the bottom of the marine food web. Phytoplankton produce half of the oxygen produced on Earth. phytoplankton stores some carbon-containing chemical compound for an indefinite period. Phytoplankton need nutrients to grow. It got its nutrients from cold water that carry nutrients from the ocean's lower depths to the surface of the ocean. Researchers study the phytoplankton from space. More phytoplankton are dying each year so more carbon dioxide are not absorbed by phytoplankton so the ocean becomes more acidic which is a danger to sea creatures. Less food is produced.
