A volcanic eruption occurs thousands of miles away but sends ash to cover the area blocking light from the sun a little bit.  The light can still reach the water in large amounts, but is less able to reach all the way to the ocean bottom.  What species is more able to get the light resource?

• Seaweed
• Phytoplankton
