Question

The greatest threat to organisms and biodiversity is}

• A. process of habitat loss
• B. species extinction all over the world
• C. reduced carrying capacity of the habitat
• D. biodiversity hot spots

Hint:

Habitat loss is the biggest threat to biodiversity—it triggers extinction and ecosystem imbalance.

Answer 1

The Correct Option is A

Concept: Biodiversity is most threatened by the destruction of natural habitats. Step 1:Understand primary threat.
Habitat loss (due to deforestation, urbanization, agriculture) leads to:

• Loss of shelter and food
• Disruption of ecosystems
• Eventual extinction of species

Step 2:Evaluate options.}

• Species extinction $\rightarrow$ Result, not primary cause
• Reduced carrying capacity $\rightarrow$ Secondary effect
• Biodiversity hotspots $\rightarrow$ Areas of high diversity, not threat

Final Answer: \[ {\text{process of habitat loss}} \]
