Question

The ability of the environment to absorb and render removal of harmless waste and pollution is referred to as:

• A. Source function of ecosystem
• B. Sink function of ecosystem
• C. Carrying capacity of ecosystem
• D. Optimal capacity of ecosystem

Answer 1

The Correct Option is B

The ability of the environment to absorb and render removal of harmless waste and pollution is referred to as sink function of ecosystem.

Additional Context:

• Sink Function Definition:
  • Natural process of absorbing, filtering, and breaking down pollutants
  • Examples: Oceans absorbing CO₂, wetlands filtering runoff
• Key Characteristics:
  • Limited capacity (varies by ecosystem type)
  • Can be overwhelmed by excessive pollution
• Other Options Analysis:
  • Source function (1): Provision of resources (food, water)
  • Carrying capacity (3): Maximum population an ecosystem can sustain
  • Optimal capacity (4): Not a standard ecological term
• Global Significance:
  • Carbon sinks (forests, oceans) crucial for climate regulation
  • Wetlands act as nitrogen/phosphorus sinks
• Threats to Sink Functions:
  • Deforestation reduces carbon sequestration
  • Ocean acidification impairs marine sink capacity

Correct Answer: (2) sink function of ecosystem.
