Question

what is the major concern regarding loss of biodiversity in agriculture? improved soil fertility loss of genetic diversity increase in wildlife decrease in crop yield

Explanation:

• "Improved soil fertility" is a positive outcome, not a concern from biodiversity loss.
• "Loss of genetic diversity" is a major concern as biodiversity loss in agriculture (like relying on a few crop varieties) reduces genetic variation, which is crucial for resilience (e.g., to pests, climate change).
• "Increase in wildlife" is not a typical concern of agricultural biodiversity loss (usually, agriculture reduces wildlife habitats).
• "Decrease in crop yield" can result from biodiversity loss, but the primary concern related to biodiversity itself is the loss of genetic diversity (the foundation of biodiversity in crops/livestock).

Answer:

B. loss of genetic diversity
