Question

1 what impact did hurricane sandy have on the beaches of the delaware bay? 2 how would a lack of sand and horseshoe crabs in delaware bay affect migrating red knots?

Explanation:

1. Hurricane Sandy likely caused beach erosion, reshaped shorelines, and may have deposited debris on the Delaware Bay beaches. It could have also disrupted coastal ecosystems.
2. Sand provides nesting and foraging areas for red knots. Horseshoe crabs are a key food - source as their eggs are a major part of the red knots' diet during migration. A lack of these would lead to reduced foraging opportunities, potential weight loss, and could impact their ability to complete their long - distance migrations and reproduce.

Answer:
