Study Notes

Ecosystem Types

  • Ecosystems are classified into various types based on their location and characteristics.
  • Natural Ecosystems: These ecosystems are naturally occurring, including forests, grasslands, deserts, and aquatic environments such as rivers, lakes, and oceans.
  • Artificial Ecosystems: These ecosystems are created or modified by humans, such as crop fields, aquariums, and zoos.

Types of Ecosystems

  • Terrestrial Ecosystems: These ecosystems are based on land. Examples include:
    • Forest
    • Grassland
    • Desert
    • Mountain
  • Aquatic Ecosystems: These ecosystems are based on water. Examples include:
    • Pond
    • River
    • Lake
    • Ocean
  • Freshwater Ecosystems: These ecosystems contain freshwater and include ponds, rivers, lakes.
  • Marine Ecosystems: These ecosystems are saltwater based. Example oceans.

Components of Ecosystems

  • Biotic Components: These are the living components of an ecosystem, including:
    • Plants
    • Animals
    • Fungi
    • Bacteria
  • Abiotic Components: These are the non-living components of an ecosystem, including:
    • Air
    • Water
    • Soil
    • Temperature
