Zooplankton
________: single- celled animals that eat phytoplankton and their waste.
Pollutants
________ can be: anthropogenic or natural, point or nonpoint source, organic or inorganic, direct or indirect.
Continental shelf
________: extension of continents under the seas and oceans (creates shallow water)
Aquaculture
________: farming aquatic organisms (coastal and inland) involving interventions in the rearing process to enhance production.
Eutrophication
________: when lakes and coastal waters receive inputs of nutrients (nitrates and phosphates) that result in an excess growth of plants and phytoplankton.
Indicator species
________: plants and animals that show something about the environment by their presence, absence, abundance.
