Which of the following statements about biodiversity are correct?
A. Biodiversity can support ecosystem stability.

B. Human activities have sharply increased species extinctions.

C. Habitat fragmentation has no adverse impact on biodiversity.

D. About 70% of all known species are invertebrates.

Choose the correct answer from the options given below:

Correct option is B

Statements A, B, and D are correct. A: Biodiversity can indeed support ecosystem stability by providing resilience to environmental changes. B: Human activities, such as deforestation, pollution, and climate change, have sharply increased species extinctions. D: About 70% of all known species are invertebrates, including insects, mollusks, and crustaceans. C is incorrect because habitat fragmentation has significant adverse impacts on biodiversity, disrupting ecosystems and increasing species vulnerability.
Information Booster: 1. Ecosystem Stability: High biodiversity contributes to ecosystem resilience and the ability to recover from disturbances.
2. Species Extinction: The current rate of species extinction is much higher than the natural background rate due to human activities.
3. Habitat Fragmentation: Leads to the isolation of species populations, reducing genetic diversity and increasing the risk of extinction.
4. Invertebrates: Make up the majority of known species, playing essential roles in ecosystems, such as pollination and decomposition.
5. Conservation: Protecting biodiversity is critical for maintaining ecosystem services, such as water purification, pollination, and carbon sequestration.
6. Biodiversity Hotspots: Regions with high biodiversity and significant threats from human activities, such as the Western Ghats in India.
