← GeographyWhich ecosystem failure initiates in limestone caves during extended drought?
A)Nutrient availability through slowed leaching✓
B)Habitat reduction via speleothem growth
C)Troglobite extinction from predator invasion
D)Food web collapse through bacterial bloom
💡 Explanation
Reduced water percolation during drought diminishes dissolved mineral transport, which results in nutrient deficiency due to leaching, because resources cannot replenish; therefore nutrient loss is correct, rather than other community changes that require more complex interactions.
