How is biodiversity important for ecosystem functioning?
✓

Answer

Biodiversity is important for ecosystem functioning because,
  1. It contributes to productivity.
  2. It cause more efficient recycling of energy and matter.
  3. It has many alternative pathways for survival under diverse conditions.
  4. Rich biodiversity provides alternatives available at each trophic level. All organisms are linked in food chains and interact with their abiotic environment in such a way so as to keep the natural cycles going and make the ecosystems self - sustaining units. Disappearance of any link in a food chain will not affect the ecosystem as other alternatives are there.
