What happens in winter?

Different strategies: Resting stages on bottom is not very important in the oceanic areas because they are too deep for upwelling. More important in coastal areas where upwelling can go all the way to the bottom. I think they have resting stages in the bottom in coastal areas so they can be brought back up with nutrients Nutrients are also brought bak up during winter.
