Bacteria
Bacteria are single-celled microorganisms that can be found in various environments, including the ocean. Some bacteria are beneficial to marine life, such as those that help break down organic matter and recycle nutrients. However, some bacteria can also be harmful and cause diseases in marine organisms. Bacteria can be transported through ballast water, which is often discharged from ships, and can lead to the introduction of invasive species and harmful pathogens into new environments. Therefore, it is important for ships to properly manage their ballast water to prevent the spread of harmful bacteria.
