Explanation:

Statement 1 and 2 are correct

The existence of phytoplankton does not alter the density or any other chemical property of water. However, if for any reason the entire phytoplankton is destroyed then it will disrupt the entire grazing food chain of aquatic ecosystem. Photosynthesis by phytoplankton fix the carbon and help the ocean behave as a sink of carbon. Therefore, statements 1 and 2 holds true and statement 3 is incorrect.
