Dead zones: algal blooms consume oxygen, kills shellfish and displaces fish. Poisonous algae and countless plants and animals have invaded harbor waters and disrupted the local ecological balance. Destruction of coral reefs. Of the seventeen major world fisheries, four are depleted and the other thirteen are either fished to capacity or over-fished. Ghost nets: lost or discarded fishing nets keep on fishing. Nitrogen and phosphorus from sources such as fertilizer, sewage and detergents, enter coastal waters. Invasive species, such as zebra mussels. Cruise ships and tourists. Commercial marine fisheries. 01 S ITEM BANK: M 2arrow_forwardMore about zonation Click on the question marks to change them to a check mark for each statement that is TRUE or a blank box if the statement is NOT TRUE about vertical zonation. Kelps and corraline algae can be found along the lower intertidal and subtidal zones. ? The lower intertidal is dominated by seaweeds. The first stage of ecological succession in the rocky intertidal is the establishment of bacteria and microscopic algae. Green, brown and red algae on the upper intertidal are able to fix nitrogen from the air. The effect of a keystone species can easily be judged by how abundant it is.arrow_forward
