Which abiotic factors are necessary for plants to survive in an aquatic ecosystem?
Abiotic factors are parts of an environment that are not alive, but that affect the ecosystem. Factors that affect aquatic ecosystems include water flow rate, salinity, acidity, oxygen, light levels, depth, and temperature. Light levels affect photosynthesizing plants and predation.
neritic zone(neritic province) The shallow-water, or near-shore, marine zone extending from the low-tide level to a depth of 200 m. This zone covers about 8 per cent of the total ocean floor and is the area most populated by benthic organisms (see benthos), owing to the penetration of sunlight to these shallow depths.
- High Tide Zone: Also called the Upper Mid-littoral Zone and the high intertidal zone. This area is flooded only during high tide. Organisms in this area include anemones, barnacles, brittle stars, chitons, crabs, green algae, isopods, limpets, mussels, sea stars, snails, whelks and some marine vegetation.
- and sea stars Temperature The Neritic Zone has an average temperature of 24 Celcius year round,and gets colder farther away from the shore.
- The largest of all the ecosystems, oceans are very large bodies of water that dominate the Earth's surface. Like ponds and lakes, the ocean regions are separated into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species.
In marine biology, the neritic zone, also called coastal waters, the coastal ocean or the sublittoral zone, refers to that zone of the ocean where sunlight reaches the ocean floor, that is, where the water is never so deep as to take it out of the photic zone.
- Which life zone is more productive, the neritic or the oceanic? Explain. The Neritic zone is more productive because rivers that contain runoff from the land flow into the neritic zone, providing nutrients for plankton.
- Sub zones. The oceanic zone is subdivided into the epipelagic, mesopelagic, and bathypelagic zones. The epipelagic (euphotic) zone, also called the sunlit zone, receives enough sunlight to support photosynthesis.
- The bathyal zone or bathypelagic – from Greek βαθύς (bathýs), deep – (also known as midnight zone) is the part of the pelagic zone that extends from a depth of 1,000 to 4,000 m (3,300 to 13,100 ft) below the ocean surface. It lies between the mesopelagic above, and the abyssopelagic below.
The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 200 meters (656 feet), seaward from the coast to the open ocean.
- In marine biology, the neritic zone, also called coastal waters, the coastal ocean or the sublittoral zone, refers to that zone of the ocean where sunlight reaches the ocean floor, that is, where the water is never so deep as to take it out of the photic zone.
- The pelagic region is divided into three zones. The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here.
- Epipelagic Zone - The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 meters (656 feet). It is also known as the sunlight zone because this is where most of the visible light exists.
