    Study Notes

    Overview of the Course

    • Explores the interaction between human activities and the natural environment.
    • Modifications in the environment can lead to significant consequences for human activity.

    Ecosystem Components

    • Composed of two primary components: biotic and abiotic.

    Biotic Components

    • All living elements within an ecosystem.
    • Classified based on nutrition:
      • Producers: Organisms like plants that synthesize food via photosynthesis.
      • Consumers: Organisms (animals) that consume other living entities for energy.
      • Decomposers: Organisms such as fungi and bacteria that break down dead matter, enriching the soil.

    Abiotic Components

    • Non-living aspects of the ecosystem.
    • Includes essential elements like air, water, soil, minerals, and light.

    Types of Ecosystems

    • Terrestrial Ecosystems:

      • Forest: Home to various plants and animals, crucial for temperature regulation and carbon storage.
      • Grassland: Dominated by grasses and herbs, includes temperate and tropical varieties.
      • Tundra: Treeless, cold areas covered in snow for most of the year.
      • Desert: Characterized by extreme temperatures and minimal rainfall, resulting in limited vegetation.
    • Aquatic Ecosystems:

      • Freshwater: Lakes, rivers, and streams with low salt content.
      • Marine: Seas and oceans with high salt content and significant biodiversity.
      • Coastal: Areas where freshwater meets saltwater, including estuaries and mangroves.

    Importance of Ecosystems

    • Healthy ecosystems are vital for:
      • Air purification for respiration.
      • Carbon regulation for climate stability.
      • Nutrient recycling for clean water access.
      • Supporting agricultural development and food security.

    Negative Environmental Impacts

    • Human activities can lead to adverse effects such as:
      • Overpopulation and resource strain.
      • Pollution and ecosystem degradation.
      • Climate change and increased natural resource conflicts.

    Connection Between People and Ecosystems

    • Human impact on the environment manifests through:
      • Urbanization, deforestation, and mining.
      • Pollution from fossil fuel combustion and improper waste management.

    Consequences of Environmental Malpractices

    • Triggers a range of global issues, including:
      • Climate change and soil erosion.
      • Poor air quality and food scarcity.
      • Health hazards and water shortages.
      • Loss of biodiversity.
