Environmental Problems Ch 7 Review
Function of Wetlands absorb and remove pollutants, trap carbon, control floods
Estuaries receive nutrients from oceans and rivers, damaged by the amount of pollution, both fresh and salt water, changes in salinity
Coastal pollution industrial waste and sewage
Swamps flat poorly drained land
Marine organisms most found in shallow coastal waters
Rivers on flatter ground they widen, warm, and slow,move faster and increase oxygen levels as they near the ocean
Threats to the ocean nutrient runoff, industrial waste, overfishing, sewage, algal blooms
Lakes and ponds organisms depend on sunlight, nutrients, temperature
Littoral zone life is diverse, found near the shore
Benthic zone cool and dark
Nekton swims freely, nekton
Benthos lives attached to a surface, barnacle
Producers phytoplankton
Wetlands many nutrients and a lot of photosynthesis, once seen as disease infested wasteland, various plants and animals
Coral reefs built by tiny marine organisms, threatened by oil spills, sewage, and pesticides, made of secreted calcium
Freshwater wetlands marshes and swamps
Salt marshes very high salt content dominated by marsh grasses
Mangrove swamp dominated by marsh grasses
Deep ocean no sunlight for photosynthesis
Arctic nutrients from the ocean
Open ocean least productive marine ecosystem
Eutrophication too many nutrients in a lake, promotes plant growth
Rhizoids attach mosses to rocks
Barrier islands long thin, run parallel to shore
Salinity amount of dissolved salts in water
Ocean pollution traced back to land
Plankton zooplankton and phytoplankton
Marsh wetland with non
Swamp wetland dominated by woody plants
Compare the benthic and littoral zones of a lake
Relationship between coral and algae how does pollution affect it?
