• benthic

• aphotic

Tropical water is very clear and blue because:

• these is very little in the way of phytoplankton or nutrients in

• the water is too warm to contain any nutrients

• fish and plant life filter the water

• the equatorial currents push out impurities

During an El Nino event, when sea surface temperatures in the eastern Pacific Ocean increase, the amount of phytoplankton, as measured using chlorophyll-a ______________________.

• increases

• decreases

• remains the same

• adjust to temperature variations
