Which of the following is an example of natural terrestrial ecosystem?

The correct answer is Grassland.

Key Points

• A grassland is an example of a natural terrestrial ecosystem characterized by vast open spaces dominated by grasses, shrubs, and few scattered trees.
• Terrestrial ecosystems are those that occur on land and include natural ecosystems like forests, deserts, and grasslands.
• Grasslands serve as habitats for a variety of flora and fauna, such as herbivores (e.g., deer, bison) and predators (e.g., lions, wolves).
• These ecosystems play a critical role in maintaining ecological balance, including carbon sequestration, soil fertility, and biodiversity preservation.
• Grasslands are found globally and are classified into types such as tropical savannas, temperate grasslands, and steppes, depending on their geographical location and climate.

Additional Information

• Natural Ecosystems:
  • Natural ecosystems develop without human intervention and are self-sustaining, such as forests, grasslands, deserts, rivers, and oceans.
  • They are categorized into terrestrial (land-based) and aquatic (water-based) ecosystems.
• Terrestrial Ecosystems:
  • These ecosystems occur on land and include forests, deserts, grasslands, tundras, and mountainous regions.
  • They are influenced by abiotic factors like soil, temperature, and precipitation.
• Aquatic Ecosystems:
  • Aquatic ecosystems are water-based and include freshwater ecosystems (rivers, lakes, ponds) and marine ecosystems (oceans, coral reefs).
  • Unlike terrestrial ecosystems, aquatic ecosystems are influenced by water chemistry, salinity, and depth.
• Human-Made Ecosystems:
  • Examples include aquariums, agricultural fields, and urban parks, which are artificially created and maintained by humans.
  • These systems require external inputs like fertilizers, irrigation, or maintenance to sustain themselves.
• Importance of Grasslands:
  • Grasslands help prevent soil erosion and serve as grazing grounds for livestock.
  • They act as carbon sinks and play a role in combating climate change.
  • They are vital for supporting both local communities and wildlife species.
