In the Arctic marine habitat, fishing has long been a way of life, Natives to the area have satiably utilized the riches of the oceans for generations. Recently a commercial fishing company has entered this area and begun bottom trawling for small fish such as sardines
and Arctic cod. How would such a fishing technique impact the ecosystem? Choose ALL that apply.
A)
Top level predators may leave the area in search of food.
B)
Overall, there will be a reduction in biodiversity in the area.
Once prey species are caught, the food web in the area will be disrupted,
DO
Predators from other regions will move in to replace absent polar bears
and seals
E)
The trawl net will scoop up everything in its path, including marine life and
Seafloor structure.
Interdependence of Organisms

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
