The average salinity of the oceans is around 3.5 ppt, which means that for every 1,000 grams of seawater, approximately 35 grams are dissolved salts. This salinity level is maintained through various processes such as evaporation, precipitation, and the input of freshwater from rivers.

    Draw a 4-link ocean food chain.

    Correct Answer
    Plankton > Fish > Penguins > Leoperd Seal
    This is a simple representation of a food chain in the ocean. Plankton is at the base of the chain, as it is a primary producer and forms the main food source for many marine organisms. Fish feed on plankton, making them primary consumers. Penguins consume fish, making them secondary consumers. Finally, leopard seals are at the top of the chain as tertiary consumers, feeding on penguins. This food chain demonstrates the flow of energy and nutrients from one organism to another in the ocean ecosystem.

The continental slope refers to the steep slope that separates the continental shelf from the deep ocean floor. The continental shelf is the shallow, submerged extension of a continent that gradually slopes away from the shoreline. Volcanoes can also be found on the ocean floor, formed by volcanic activity and creating underwater mountains.
