Nutrient availability is important for the affects of distribution and abundance of organisms in an aquatic biome A. Explain ocean upwelling B. Explain lake turnover 3. Define these terms in a freshwater zone: Littoral zone-shallow waters along the shore, where flowering plants are rooted Limnetic zone-offshore and comprises water that receives enough light to support photosynthesis Benthic zone-made up of the bottom/substate Photic zone-regions that receive sunlight Aphotic zone-regions that do not receive sunlight 4. Define these terns in an ocean zone: Intertidal zone-consists of a beach that is exposed to air at low tide, but submerged at high tide Neritic zone-extends from the intertidal zone to the continental shelf (the gently sloping, submerged portion of the continental plate) Oceanic zone-the open-open ocean, deep water region beyond the continental shelf Benthic zone-the bottom of the ocean Photic zone-“ ” Aphotic zone-“ “ 5.
