Unit 8 Quizs

Phytoplankton

• Floating algae.

• Sedimentary rocks.

• Deep-sea fish.

• Coral reefs.

Mangrove swamp

• A type of forest found in temperate regions

• A swamp that occurs along tropical and subtropical coasts and contains salt-tolerant trees with roots submerged in water.

• A freshwater wetland dominated by grasses and reeds

• A coastal area characterized by rocky shorelines and tidal pools.

Open ocean

• Deep-ocean water, located away from the shoreline where sunlight can no longer reach the ocean bottom.

• Shallow coastal waters where sunlight penetrates to the ocean floor.

• Areas of the ocean that are rich in nutrients and support diverse marine life.

• Regions of the ocean that are heavily polluted and devoid of life.

Freshwater biomes

• Categorized as streams and rivers, lakes and ponds, or freshwater wetlands.

• Characterized by high salinity levels and tidal movements.

• Found only in tropical regions and characterized by coral reefs.

• Consist mainly of saltwater and are home to marine life.

Limnetic zone

• A zone of open water in lakes and ponds as deep as the sunlight can penetrate.

• A shallow area near the shore of a lake or pond.

• A zone of water where light does not penetrate, typically found at great depths.

• An area of land that is periodically flooded with water.

Coral bleaching

• A phenomenon in which algae inside corals die, causing the corals to turn white.

• A process where corals gain color due to increased algae growth.

• A type of coral that thrives in warm waters.

• A method of coral reproduction that involves external fertilization.

Oligotrophic

• Describes a lake with a high level of phytoplankton due to high amounts of nutrients in the water.

• Describes a lake with a low level of phytoplankton due to low amounts of nutrients in the water.

• Describes a lake that is rich in organic matter and supports diverse aquatic life.

• Describes a lake that is heavily polluted and has low oxygen levels.

Primary treatment

• Chemical treatment of wastewater

• Physical removal of large debris (Toilet paper, leaves, plastic, sediment) with a screen or grate.

• Biological treatment using microorganisms

• Filtration through sand and gravel

Tertiary treatment

• A process that involves only physical methods to treat wastewater.

• Ecological or chemical treatments to reduce pollutants left after primary and secondary (Nitrogen, Phosphorus, bacteria).

• A method used exclusively for solid waste management.

• A preliminary step in the wastewater treatment process.

Mesotrophic

• Describes a lake with a moderate level of fertility.

• Describes a lake with a high level of fertility.

• Describes a lake with a low level of fertility.

• Describes a lake that is devoid of life.
