Coastal waters often support larger blooms of plankton than open water due to a high nitrate level in
runoff. Indicate whether the statement is true or false.
ANS: T
The runoff from the land is able to support large plankton blooms. Nitrates, the highest of the nutrients
in runoff waters, are used in various agricultural settings and enter the ocean. Some of these areas can
become oxygen depleted due to the sudden bloom of plankton dying and bacteria decomposing them.
