0 Points: 0 of 1 Marine life is dependent upon the microscopic plant life that exists in the photic zone, a zone that goes to a depth where about 1% of the surface light remains. In some waters with a great deal of sediment, the photic zone may go down only 15 or 20 feet. In some murky harbors, the intensity of light d feet below the surface is given by l= ID 6 '0-32". where I0 is the intensity or light at the surface. What percentage of the surface light will reach a depth of (A) 5 feet? (B) 10 feet? (A) The percentage of surface light at 5 feet is} A. (Round to the nearest percent as needed.) nu-mnnm \\ 533mm i new
