The diagram below shows a typical NSW coastal food web. Sea Starfish urchins Algae on госks Sea birds Limpets. Crabs Mulberry whelks Periwinkle Carnivorous fish Phytoplankton (microscopic plants) Zooplankton (microscopic animals Tube worms Primary Consumers Secondary Consumers Tertiary Consumers Producers There has been an increase in the amount of larger sea urchins being removed from the area by people wanting them for food and bait. The smaller ones are harder to remove from the rock crevices where they attach and so they are not collected. (a) Outline the impact on the Mulberry Whelk population if people continue to remove the sea urchins.

Which of the following statements about nutrient inputs and eutrophication is FALSE? O Fossil fuel combustion (e.g. burning gasoline, coal) releases nitrogen which contributes to eutrophication The production of chemical farm fertilizers through industrial fixation of N, is a major source of bioavailable nitrogen and cause of eutrophication O The mining of phosphate rock for fertilizers is a major source of bioavailable phosphorus and cause of eutrophication O Eutrophication can cause oxygen depletion in aquatic systems by increasing the growth of algae which consume a lot of oxygen The production of livestock at large-scale (which generates a lot of manure) can be a cause of eutrophication
