Streams and rivers carry dissolved salts and minerals into the oceans. When water evaporates from the ocean surface, salts and nutrients are left behind as they do not evaporate with the water. Organisms do not significantly contribute to ocean salinity through releasing salty waste in the main - factor sense.

Answer:

• streams and rivers carry dissolved nutrients into oceans
• when water evaporates, nutrients do not evaporate with it
