Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biodiversity encompasses the variety of life forms on Earth, including their genetic variation, species diversity, and ecosystem diversity. It is crucial for the functioning of ecosystems, providing essential services such as nutrient cycling, pollination, and water purification. Biodiversity also supports human livelihoods, including food production, medicine, and tourism.

Multiple choice

How does biodiversity contribute to the stability and resilience of ecosystems?

  1. Biodiversity provides functional redundancy, where multiple species perform similar ecological roles.

  2. Biodiversity enhances ecosystem resilience by increasing the diversity of genetic traits and adaptations.

  3. Biodiversity promotes ecosystem stability by reducing competition among species for resources.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biodiversity contributes to ecosystem stability and resilience through functional redundancy, genetic diversity, and reduced competition. Functional redundancy ensures that ecosystem functions are maintained even if one species is lost or declines. Genetic diversity provides the raw material for adaptation and evolution, allowing ecosystems to respond to changing environmental conditions. Reduced competition promotes species coexistence and enhances the overall stability of the ecosystem.
