Question

a developer proposes to drain an estuary, and then use the land to build an ocean - side hotel, houses and parking lots. which would be the most likely effect of the new development on the local ecosystem? a. loss of spawning and nursery grounds for many fishes and shellfish b. death of coral animals and loss of the coral reef ecosystem c. reduction of primary productivity for the ocean ecosystem d. increased salinity of ocean water

Explanation:

Estuaries are crucial spawning and nursery areas for many marine species. Draining an estuary would directly lead to the loss of these important habitats. Coral reefs are not directly affected by estuary - draining. Primary productivity in the ocean is not mainly tied to estuaries in this context, and the salinity of ocean water is not likely to be significantly affected by draining one estuary.

Answer:

A. loss of spawning and nursery grounds for many fishes and shellfish
