On a trip to a dense forest, a biologist noticed that millipedes (small invertebrates) were plentiful under logs but were rarely seen in any other location. a) Propose ONE environmental variable that could explain why millipedes are found more frequently under logs. (1 pt) b) For the variable that you identified, design a controlled experiment to test a hypothesis that this factor affects the distribution of millipedes on the forest floor. Include the following: i) State the hypothesis (1 pt) ii) Describe the method you would use to test your hypothesis (1 pt) iii) Identify the control (1 pt) ) Identify the dependent variable (1 pt) c) Describe experimental results that would lead you to reject your hypothesis in b. (1 pt) d) Explain why forests are considered to be a renewable resource. (1 pt) Besides fossil fuels, give an example of a resource that is non-renewable. (1 pt) e) (1 pt) Identify another resource that could be harvested unsustainably. (1 pt)
