Question

Analyze the relationship between species diversity, productivity, and stability. Which statements are true?

1. Species diversity is generally inversely proportional to the productivity of an ecosystem.
2. Higher species diversity typically leads to increased ecosystem stability.
3. Ecosystem productivity tends not to be proportionate to its species diversity.

• A. ii only
• B. ii, iii
• C. iii only
• D. None of these

Answer 1

Answer:

A. ii only

• Ecological studies generally support the idea that greater species diversity enhances both the productivity and stability of an ecosystem.

• A diverse community offers a wider range of functional traits, improving resource utilization and resistance to disturbances.

• For instance, a diverse plant community can better withstand disease outbreaks or extreme weather events, while different species might thrive under varying conditions, ensuring overall productivity remains high.

• This relationship is a cornerstone of biodiversity conservation efforts.
