Rather than assuming general ecological patterns hold true for this deep sea vent community, you decide to look at production efficiency in depth.  You discover that a rat fish that consumes 500J of shrimp typically loses about 300J to cellular respiration.  Another 100J is excreted as waste.  The remaining 100J is used for growth (incorporated into the rat fish’s body tissues).  Given this, which equation best matches the rat fish’s production efficiency?  

In the experiment from the previous question, what types of species would you expect to find in the undisturbed cylinders? [ans1] What types of species would you expect to find in the cylinders that were disturbed every six days?

To support species native to Australia, Arid Recovery has created a relatively cat-free preserve by fencing and eliminating cats from a sanctuary.  Here is a photo of the set up and an adorable native Australian stick-nest rat from Arid Recovery’s website. Based on the success of the project, they plan to expand their program to protect more land from cats.  Imagine you are an ecologist consulting with them on this expansion.  List 3 suggestions you would make to the team as they consider the size, shape and/or location of additional protected land.  Back up each suggestion by briefly explaining the ecological principle it is based on.   1.  Suggestion 1 with supporting ecology principle. (3 points) 2.  Suggestion 2 with supporting ecology principle.  (3 points) 3.  Suggestion 3 with supporting ecology principle (3 points)
