Learn about the definition and characteristics of aquatic ecosystems, and discover different types of aquatic ecosystems. The upper section down to about 80 m is the euphotic zone which receives enough solar radiation to allow photosynthesis to occur. Sunlight produces Photic or Epipelagic Zone Characteristics of Prochlorophytes. Occasionally large items like dead sharks or whales arrive, but generally food is scarce. ANSWER: Correct "Photic" means light, and light encourages the growth of photosynthetic organisms. 10 What lives in the oceanic zone? Which of these characteristics is shared by algae and seed plants? Deep Sea Creatures refer to organisms that live below the photic zone of the ocean. . This zone has enough light for organisms to carry out the process of photosynthesis. The zone in which too little light penetrates to support photosynthesis is known as the aphotic (or profundal) zone. These include the litoral zone, which is the area along the shoreline where rooted plants grow; the pelagic zone, or the area we call open water; the photic zone, where sunlight reaches underwater; and the aphotic zone, where sunlight doesn't reach. It is formally defined as the depths beyond which less than 1 percent of sunlight penetrates. The mesopelagic zone is the layer of the ocean from the range of 200 meters to 1,000 meters (656 feet to 3,281 feet). About 90% of all marine life lives in the photic zone.

Phytoplankton and other algae are abundant in the euphotic zone and are able to use sunlight to make sugars through photosynthesis. The photic zone is the surface layer of the oceans or water bodies. The size of the light distortion compared to the total area under evaluation, also known as the light distortion index (LDI%), was calculated. Benthic zones exist all over the world in every appreciable water system, be it an ocean, lake, pond, river, or stream. Less food means lower biomass. Profundal Zone or Aphotic Zone. The erosive power of water current results in unique landform, such as estuaries. The more organic matter in the pond, the more decomposition taking place. Other articles where aphotic zone is discussed: inland water ecosystem: Population and community development and structure: …in both the photic and aphotic zones. All of the ocean's open water is referred to as the pelagic realm (or zone). Within the pelagic realm is the photic zone, which is the portion of the ocean that light can penetrate (approximately 200 m or 650 ft). Oceans change temperature more quickly than the land changes temperature. The photic zone is the top part of the water through which sunlight does pass. Since tiny photosynthetic organisms, known as phytoplankton supply nearly all of the energy and nutrients to the rest of the marine food web, most other marine organisms live in or visit the photic zone. At depths greater than 200 m, light cannot penetrate; . Beneath the pelagic zone is the benthic realm, the deep-water region beyond the continental shelf (). Oceans have a high heat capacity and change temperature slowly. The uppermost 80 m (260 feet) or more of the ocean, which is sufficiently illuminated to permit photosynthesis by phytoplankton and plants, is called the euphotic zone.
