Across2. A fishing net made of monofilament fishing line that catches organisms by entanglement. (8)
4. Any loose material produced directly from rock disintegration, or material resulting from the disintegration of dead organic remains. (8)
5. Algal plankton. One of the most important communities of primary producers in the ocean. (13)
6. A layer that extends from the surface of the ocean to a depth where enough light exists to support photosynthesis, rarely deeper than 100 m. (12)
7. The process by which plants and algae produce carbohydrates from carbon dioxide and water in the presence of chlorophyll, using light energy and releasing oxygen. (14)
8. A reddish-brown discoloration of surface water, usually in coastal areas, caused by high concentrations of microscopic organisms, usually dinoflagellates. Toxins produced by the dinoflagellates may kill fish directly, or it may lead to an indirect depletion of oxygen which can asphyxiate many animals. (7)
9. The _______ pyramid is a representation of trophic levels that illustrates the progressive decrease in total biomass at successive higher levels of the pyramid. (7)
11. A group of interrelated food chains. (7)
12. The rate at which energy is stored by organisms through the formation of organic matter using energy derived from solar radiation (photosynthesis) or chemical reactions (chemosynthesis). Also known simply as productivity. (19)
13. Another term for red tide. (17)
15. A situation that occurs when adult fish in a population are harvested faster than their natural rate of reproduction. (11)
18. An animal within an ecosystem that consumes the organic mass produced by the producers. (8)

Down1. Marine organisms that are caught incidentally by fishers seeking commercial species. (7)
3. The enrichment of waters by a previously scarce nutrient. (14)
4. A region of hypoxic conditions that kills off most marine organisms that cannot escape. It is usually the result of eutrophication caused by runoff from land-based fertilizer applications. (8)
10. The _______ yield is the maximum fishery biomass that can be removed yearly and still be sustained by the fishery ecosystem. (18)
11. The passage of energy materials from producers through a sequence of a herbivore and a number of carnivores. (9)
14. Primarily bacteria that break down non-living organic material, extract some of the products of decomposition for their own needs, and make available the compounds needed for primary production. (10)
16. Another term for driftnet. (7)
17. The autotrophic component of an ecosystem that produces the food that supports the biocommunity. (8)
