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? |
