1/15
  • Net Primary Production
    Represents the amount of organic material produced by autotrophs after accounting for their own energy use.
  • Light Penetration
    Determines how deeply sunlight reaches in water, directly influencing photosynthesis rates in aquatic environments.
  • Limiting Nutrient
    A substance, often nitrogen or phosphorus, whose scarcity restricts the growth and productivity of an ecosystem.
  • Nitrogen
    An essential element for growth, often in short supply, that can boost productivity when added to ecosystems.
  • Phosphorus
    A key nutrient required for energy transfer and growth, frequently limiting in both aquatic and terrestrial systems.
  • Eutrophication
    A process where nutrient enrichment leads to increased productivity and subsequent oxygen depletion in water bodies.
  • Oxygen Depletion
    A reduction in dissolved oxygen, often resulting from the breakdown of organic matter after a productivity surge.
  • Detritus
    Dead organic material that sinks in water, carrying nutrients to deeper layers and influencing nutrient gradients.
  • Root Nodule
    A specialized plant structure housing bacteria that convert atmospheric nitrogen into a usable form for plants.
  • Nitrogen-Fixing Bacteria
    Microorganisms living in association with plants, transforming inert nitrogen gas into biologically accessible compounds.
  • Tropical Rainforest
    A terrestrial ecosystem with consistently high moisture and temperature, supporting the highest productivity levels.
  • Desert
    A biome characterized by low precipitation and productivity, often with extreme temperatures.
  • Tundra
    A cold, dry terrestrial ecosystem with minimal productivity due to limited moisture and low temperatures.
  • Coral Reef
    A highly productive aquatic ecosystem, supporting diverse life despite occupying a small area.
  • Open Ocean
    A vast aquatic region with low productivity per unit area but significant total output due to its immense size.
