  • Oligotrophic Lake
    A body of water with low nutrient levels, high oxygen content, clear and cold water, and limited primary productivity.
  • Eutrophic Lake
    A nutrient-rich, oxygen-poor water body with abundant plant and algae growth, often resulting in murky water and high productivity.
  • Primary Productivity
    The rate at which photosynthetic organisms produce organic compounds, influencing ecosystem energy flow.
  • Decomposition
    The breakdown of organic matter, consuming oxygen and impacting oxygen levels in aquatic environments.
  • Tributary
    A smaller flowing water body that contributes water to a larger river or stream.
  • Wetland
    Land saturated with water, either permanently or periodically, supporting diverse plant and animal life.
  • Marsh
    A type of wetland dominated by herbaceous plants and characterized by standing or slow-moving water.
  • Swamp
    A wetland with saturated soils, often featuring woody plants like trees and shrubs.
  • Bog
    A wetland with acidic, nutrient-poor water, often supporting mosses and unique plant species.
  • Fen
    A wetland with alkaline, mineral-rich water, supporting grasses, sedges, and other specialized plants.
  • Emergent Vegetation
    Plants rooted underwater but extending above the surface, common in wetlands and crucial for habitat structure.
  • Estuary
    A coastal zone where freshwater from rivers mixes with saltwater from the ocean, creating dynamic salinity conditions.
  • Salinity
    The concentration of dissolved salts in water, varying in estuaries due to tidal influences.
  • Stream
    A small, flowing freshwater body, typically narrower and shallower than a river.
  • River
    A large, flowing freshwater body with greater volume, width, and depth, often fed by multiple tributaries.
