Which ecosystem effect occurs at high tephra fallout?

💡 Explanation

High tephra fallout smothers aquatic habitats because increased suspended sediment from waterway siltation reduces light penetration harming photosynthesizers. The stream is now uninhabitable, therefore siltation is the effect, rather than changing nutrient levels or reflectivity.
