Answer:
Coastal and open-water ecosystems
Explanation:
Organic material manufactured in estuarine communities is exported to coastal and open water ecosystems. This organic material is very beneficial to these ecosystems as it allows many nutrients to float in the changing tides. These nutrients are a very rich food source for coral reefs and kelp forests. Furthermore, these nutrients arrive in the ecosystem in the form of debris that can serve as breeding grounds for very important organisms in the region and that serve to maintain the food chain.
