EP Ch 7
| Question | Answer |
|---|---|
| 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? |
