(e)(ii) Describe an environmental problem that can result in an ecosystem after a species extinction. {Ans: -The food chains/webs of an ecosystem can be disrupted or collapse. -A trophic cascade can occur where one trophic level is suppressed leading to a dramatic change in ecosystem structure/nutrient cycling/predator-prey relationships -If the species is a keystone species, the entire ecosystem can collapse or change dramatically. -The unique genetic information of the species is lost.}(e)(iii) Many ecologists argue that establishing large preserves is the single best strategy for preventing an endangered species from becoming extinct. Justify this strategy by explaining an additional benefit, other than preventing the endangered species from becoming extinct. {Ans: -Protects overall high biodiversity in the area by protecting other species as well as the threatened/endangered species. -In a terrestrial preserve, the habitat protects water quality by protecting vegetation in the preserve, which reduces erosion and filters impurities from runoff. -In a terrestrial preserve, vegetation can sequester carbon which reduces the levels of carbon dioxide in the atmosphere. -In an aquatic preserve, protecting marine breeding grounds of commercial species can benefit the fishing industry.}(b)(i) Based on the data in the graph, identify the average growth rate of Kudzu
