Question

The following exercise requires you to fill out Table 3 (Answer sheet provided). In Table 3, you are given a set of locations on Earth that are considered extreme environments (Environment column). A link to a page with details about each of the locations is also provided. Based on the information you find, determine the most likely types of organisms (Extremophiles) that might live in each location listed and provide a brief (point form) justification for why you chose them (Reasoning). When filling out the Reasoning column, be as specific but brief as possible. For example, if you chose acidophile for a location, your reasoning point could be ‘river waters have pH 2.2’. If a specific value such as pH or temperature is not available, either use descriptive terms from the text of the information (e.g., alkaline, very low pH). Be aware that there may be more than one type of extremophile that is suited for each environment. Find at least 1 type of extremophile for each of the 6 locations beyond the example. Find homes for a total of 10 different extremophile types amongst the locations. You can use the same extremophile type in multiple locations. Provide at least one reason for each extremophile chosen. See the first row (Rio Tinto) for an example.
