Today I learned in my Ecology class the different kind of forests, and a lot about oceans. I specifically was interested by phytoplanktons because they can only live in the euphotic zone. The reason for this is that the water needs to be able to reach sunlight so they are able to do photosynthesis. They are similar to terrestial plants because they need photosynthesis to grow. They remind me of a buoy that you use swimming, because all they do is float and absorb sunlight. They also require nutrients from the ocean such as nitratees, phosphates and sulfur, because they then convert them into proteins, fats and carbohydrates. In a well balanced ecosystem, they provide food for sea animals such as whales and shrimp. The reason why I find them so cool is because they are the foundation of the sea life. They do however have toxis effects to humans!
