Organize a stream, river, bay, or beach cleanup; get your local press to cover wetland stories; or invite an expert to speak at your school or community group. The depth varies from intertidal zone (a zone covered by water only part of the time) to depth as great as 35,400 feet or 6. Take action. ‘Marine’ is a word that describes oceans and seas, where water is salty. When habitat disappears, so do plants and animals. (a) List three major zones in the marine habitat stating one characteristic feature of each zone. Marine Protected Areas (MPAs): marine sites such as sanctuaries, fisheries management areas, state conservation areas, and wildlife refuges established to protect habitats, endangered species, and to restore the health of marine ecosystems in areas jeopardized by habitat and species loss. The flora in the pelagic zone include surface seaweeds. The benthic zone is the area below the pelagic zone, but does not include the very deepest parts of the ocean (see abyssal zone below). The physical features of the marine habitat are relatively stable. The deep sea, sea floor, and open oceans would have the least access to phytoplankton. Marine ecosystems are aquatic environments with high levels of dissolved salt, such as those found in or near the ocean. (ii) Explain how each of the plant and animal is adapted to the habitat. Marine ecosystems are defined by their unique biotic (living) and abiotic (nonliving) factors. The fauna include many species of fish and some mammals, such as whales and dolphins. The three major zones of a lake described as follows (Fig. What are marine habitats? Solutions of Marine Habitat Loss and Destruction. The seas, oceans and bays have occupied about 70% of the earth’s surface. Marine Habitat: The marine habitat is the largest of all habitats. Many feed on the abundant plankton. Water/Pelagic environment consists of two major marine ecosystems, Neritic and Oceanic zones. Over 70% of the Earth’s surface is covered water, and nearly all of that is saltwater from oceans and seas. The marine ecosystems can broadly be classified into two main categories constituting 5 major marine ecosystems. Three major zones are recognized: supralittoral (covered only during highest spring tides), littoral or intertidal (covered regularly between high and low tides), and sublittoral (never exposed even during the lowest low tides). Type # 1. (a) Littoral zone: The littoral zone adjoins the shore (and is thus the home of rooted plants) and extends down to a point called the light compensation level, or the depth at which the rate of photosynthesis equals the rate of respiration. 4.9).
