Which of the following areas could you expect to find a great deal interdependence between marine and terrestrial food webs?

You would expect to find a great deal of interdependence between marine and terrestrial food webs in areas where coastal ecosystems are present. Here's why:

* Coastal Ecosystems: These are the areas where the land meets the sea, and they encompass a variety of habitats like beaches, salt marshes, estuaries, and mangroves. They serve as critical transition zones where:

* Marine Organisms: Many marine species, especially those in their early life stages, rely on coastal habitats for food, shelter, and breeding grounds.

* Terrestrial Organisms: Land-based animals, like birds and some mammals, depend on coastal areas for food (fish, invertebrates, and other marine life) and nesting sites.

* Nutrient Exchange: Coastal ecosystems are incredibly productive due to the mixing of freshwater and saltwater, which brings nutrients from both land and sea. These nutrients support both marine and terrestrial food webs.

Examples of Interdependence:

* Birds: Many coastal birds, like gulls and herons, feed on fish, crustaceans, and other marine organisms, contributing to marine food webs. However, they also bring marine nutrients to land through their droppings, supporting terrestrial ecosystems.

* Sea Otters: Sea otters are keystone species in kelp forests, helping to control sea urchin populations that can decimate kelp. This, in turn, benefits fish and other organisms that rely on kelp forests, impacting both marine and terrestrial food webs.

* Detritus: Dead plants and animals from both land and sea decompose in coastal areas, providing nutrients that support both marine and terrestrial organisms.

Other areas might show some interdependence, but not as much:

* Deep Sea: While connected to coastal areas through currents and nutrient cycles, the deep sea has a unique food web less directly impacted by terrestrial ecosystems.

* Open Ocean: The open ocean is largely self-contained, with its own food web primarily dependent on phytoplankton. However, some marine mammals and birds that rely on open ocean food webs may forage near the coast and interact with terrestrial ecosystems.

In summary, coastal ecosystems are the most likely areas to exhibit significant interdependence between marine and terrestrial food webs.
