Explain the role of water in ecosystems.

Explanation should include

  • definition of water (the key element for sustaining life and the foundational building block supporting the biochemistry of all life on the planet)
  • the water cycle
    • evaporation
    • transpiration
    • sublimation
    • condensation
    • transportation
    • precipitation
    • deposition
    • infiltration
    • surface flow
    • plant uptake
  • water’s unique properties (e.g., capillary action, surface tension)
  • photosynthesis
  • plant growth and development
  • organisms living within aquatic habitats
    • animalia
    • archaebacteria
    • eubacteria
    • protista
    • fungi
    • plantae
  • water as a breeding environment
  • the role it plays in weather and climate
  • the role of frozen water in Earth’s systems (glaciers and ice caps as a long-term storage system).

Process/Skill Questions:

  • Why is water necessary for life processes?
  • How do plants use water in photosynthesis and respiration?
  • Why do plants need water in photosynthesis?
  • How long does water remain in this reservoir of the water cycle?
  • What factors may or may not be contributing to water remaining for longer or shorter periods of time in this reservoir of the water cycle?
  • What are the implications of the decrease in ice caps and glaciers?
