    Study Notes

    Ecosystems

    • Definition: A community of living (biotic) and non-living (abiotic) components interacting with each other in a specific environment.
    • Components:
      • Biotic factors: plants, animals, microorganisms
      • Abiotic factors: light, temperature, water, soil, air
    • Types of ecosystems:
      • Terrestrial: forests, grasslands, deserts
      • Freshwater: rivers, lakes, wetlands
      • Marine: coral reefs, estuaries, open ocean
      • Arctic/Antarctic: tundra, ice sheets

    Biodiversity

    • Definition: The variety of different species of plants, animals, and microorganisms that live in an ecosystem or on Earth as a whole.
    • Types of biodiversity:
      • Genetic diversity: variety of genes within a species
      • Species diversity: number of different species in an ecosystem
      • Ecosystem diversity: variety of ecosystems in a region
    • Importance of biodiversity:
      • Maintains ecosystem services: pollination, pest control, climate regulation
      • Provides medicinal and food resources
      • Supports human well-being and quality of life
    • Threats to biodiversity:
      • Habitat destruction and fragmentation
      • Climate change
      • Overexploitation of resources
      • Invasive species
      • Pollution
