Explanation
12th NCERT Page No. 222 The major causes of biodiversity loss include: • A. Overexploitation – Excessive use of species (e.g., overfishing, deforestation). • B. Co-extinction – When the extinction of one species leads to the extinction of another (e.g., a parasite or a pollinator). • D. Habitat loss and fragmentation – One of the most critical drivers of biodiversity loss globally. Why not C (Mutation)? Mutation is a natural process and often contributes to genetic diversity, not loss. It can occasionally lead to harmful traits but is not a primary cause of biodiversity loss.
