• rejected resource

The eutrophication of a water supply can lead to a phytoplankton bloom. The excess nutrients allow these microscopic organisms to reproduce at a faster rate than normal. What is one ecological problem that can occur as a result of these blooms?

• The reduction of fish populations as oxygen levels in the water decline

• Fertilizers become less effective causing an increase in their use by farmers

• The increase in photosynthesis reduces the solar energy available to terrestrial plants
