What happens to the seaweed when the tide comes in?

When the tide comes in, seaweed that is typically exposed during low tide becomes submerged underwater. This allows the seaweed to access nutrients and sunlight, which are essential for its growth and photosynthesis. Additionally, the rising tide can help disperse the reproductive spores of the seaweed, aiding in its propagation. As the tide recedes, the seaweed returns to the intertidal zone, where it may again be exposed to air and sunlight.
