Question

Explain the interaction of living beings and non leving beings in a marine ecosystem EX: fish pond?

Answer 1

Intertidal Zone: This area is the beach with its sand and wave action though some are very rocky and void of sand. It is a harsh environment to live in and is under constant change. The tide plays an important role in how plants and animals survive in this area. Few plants are found in this area due to tidal action. Animals are mostly burrowers and filter feeders.



Neritic Zone: In tropical areas coral reefs are found in this area immediately after the intertidal zone. Since coral and algae form a mutualistic relationship by having the algae provide them with the by products of photosynthesis and they in turn provide them shelter and support.



Pelagic zone: This area is considered the open ocean. It is vast and contains very little nutrients. Phytoplankton are abundant here and produce most of the world's oxygen. Zooplankton (small arthropods, copopods, jellyfish, etc.) are also found here. In the deeper areas of the ocean animals called nekton are found. These squid, sea mammals, fish, and reptiles swim freely to find food.



Fresh Water Biome:



The freshwater biome is also divided horizontally and vertically. The horizontal divisions include the littoral zone which is closest to the shore of the lake. The limnetic zone encompasses the open area of the lake. Vertically you have the photic and aphotic zones and the benthic zone still makes up the lake floor. The deep vertical zone is called the profundal zone. Lakes are classified as Oligotrophic (deep and nutrient poor) and Eutrophic (shallower and rich in nutrients). Since there are no absolutes in ecology, a third lake type is recognized the mesotrophic lake. This is a middle ground between the two extremes.



Wetlands:



Marshes, bogs and swamps are examples of this type of biome. These areas are either permanently flooded or periodically flooded. They contain aquatic plants and animals and are considered one of the nutrient rich biomes. Under federal and state law many of these areas are protected from commercial or private development.



Estuaries:



These are areas where the marine and freshwater environments come in contact with each other. This biome is a very nutrient rich and productive environment. Algae, phytoplankton, and marsh grass are the major producers in this environment. Many invertebrates (clams,worms,and crabs) along with fish makes up its animal complement. This biome is under a tremendous stress from development and pollution.
