Chapter 11 Questions Chapter 11 Question 1 Describe the collapse of the cod fishery in the northwest Atlantic and some of its side effects Collapse: The overfishing through Industrial fish harvesting methods caused the collapse of Cod in the Northwest Atlantic in 1992. Side effects: Severely damaged New Finland?s economy, 20,000 fishermen out of work, Cod population still has not recovered, lead to collapse of other species such as sharks. Describe the effects of trawler fishing, purse-seine fishing, longlining, and drift-net fishing. Trawler fishing: Used to catch fish and shellfish that live on or near the ocean floor. Involves a funnel-shaped net along the ocean floor. Destroys ocean floor habitats.

Chapter 8 aquatic life zones The aquatic equivalents of biomes are called aquatic life zones. benthos The third type, benthos, consists of bottom dwellers such as oysters, which anchor themselves to one spot; clams and worms, which burrow into the sand or mud; and lobsters and crabs, which walk about on the sea floor. coastal wetlands coastal land areas covered with water all or part of the year coastal zone the warm, nutrient-rich, shallow water that extends from the high-tide mark on land to the gently sloping, shallow edge of the?continental shelf. coral reefs form in clear, warm coastal waters of the tropics and subtropics. cultural eutrophication

Christian Boujaoude August 17, 2014 AP Environmental Science Pd. 10 Daly FRQ Chapter 1 1. a.) A feasible explanation for the algal bloom in the pond could be that there was too much fertilizer applied to the lawn. Some of the run-off from the rain flowed down the lawn and went into the pond. This would then increase the nutrient supply in the pond and resulted in the algal bloom a few weeks later.

Invertebrates sponges, segmented worms, echinoderms, mollusks, and arthropods They do not have backbones or internal skeletons.? Some have external skeletons, called exoskeletons ??? Sponges -Very simple animals that have many pores (holes) through which water flows. -Water moves into a central cavity and out through a hole in the top. -obtain their food and eliminate wastes through this passage of water. -They have specialized cells for obtaining food and oxygen from the water. ??? Cnidarians -Hollowed-body animals with cells organized into tissues. -Have tentacles surrounding their mouth that contain stinging cells used to help capture its prey. -Have radial symmetry and two different body forms: polyp and medusa. -Examples are sea anemones, hydra, corals, and sea jellies. ???

Oceans Oceanography Study of the physical ocean Cover 71% of the Earth Contains 97% of its surface water Marine Ecosystems Cover 70% of the Earth?s surface Essential for: Biodiversity, Terrestrial Health, Production of O2, Climate and Food. Estuaries Coastal Partly enclosed One or more rivers flow into them Water is brackish (a mixture of fresh and salt water) Estuaries are among the most productive ecosystems on Earth Makes lots of biomass Lots of plant growth/m2 A lot of life in the area Nurseries for fish, crustaceans and vertebrates Services Aquatic nurseries Protected harbors Commercial Fishing, Recreational Fishing Habitat for non-aquatic animals, such as bald eagles, shorebirds Threats Many near populated areas May be filled for development Pollutants

Ecology is the scientific study of the interactions between organisms and the environment. 2. Study Figure 52.2 in your text. It shows the different levels of the biological hierarchy studied by ecologists. Notice also the different types of questions that might be studied by an ecologist at each level of study. Use this figure to define or explain the following terms: organismal ecology: Organismal ecology, which includes the subdisciplines of physiological, evolutionary, and behavioral ecology, is concerned with how an organism?s

Primary production - are photoautotrophs, capturing energy from the sun. Energy flows from these guys through all other levels. Of course some energy will be lost at each level. -light energy converted to chemical energy by autorophs during a given time period. -Gross primary production is the total primary production. -Net primary production is GPP minus energy used by producers (respiration)-only this is available to consumers. NPP is more important then GPP. Secondary production

The Magnuson- Stevens Act Tessa and Mallory Actually the Magnuson-Stevens Fishery Conservation and Management Act Sets up eight Regional Fishery Management Councils that work to manage their regions? fisheries. Enacted in 1976 when the issue of foreign fishers depleting US fish supplies came to surface Mostly known for the regulation saying that only US fishing boats could fish within 200 miles of our shore Annual Catch Limits (known as ACLs) were put up to ensure that fish supplies were not depleted too much, or beyond repair, in a single year. The ACL also limited sale, catch and transport of some specific fishes. Acceptable Biological Catches (ABCs) are very similar to ACLs; they regulate fish catch amounts. The MSA also regulated fishing equipment/technology, and vessel permits.
