Consequences of Not Treating Ballast Water
- If ballast water is not treated, it can lead to the introduction of invasive species, which can cause significant ecological, economic, and social impacts.
Characteristics of Plankton
- Plankton are tiny, usually microscopic, organisms that drift in the water column, and are an essential component of aquatic food webs.
Examples of Nekton
- Nekton are actively swimming organisms, and examples include fish, squid, and dolphins.
Difference between Epifauna and Infauna
- Epifauna are organisms that live on the surface of the sediment, whereas infauna are organisms that live within the sediment.
