 * 1) What is an ecosystem and why would we study energy flow in relation to the ecosystem?
 * 2) Label the diagram below.
 * 1) Why are detrivores essential to an ecosystem?
 * 2) Define the following terms:
 * 3) Gross primary production
 * 4) Net primary production
 * 5) How do light limitations and nutrient limitations impact primary production?
 * 6) What is eutrophication and is it considered a “positive” for the a lake environment?
 * 7) What impacts evapotranspiration?
 * 8) What is secondary production?
 * 9) Why is the energy transfer between trophic levels limited?
 * 10) What is the difference between production efficiency and tropic efficiency?
 * 11) What is the green world hypothesis?
 * 12) Complete the diagram below of the general model of nutrient cycling.
 * 1) Briefly detail the water cycle. You can write this response or draw the cycle.
 * 2)  Briefly detail the carbon cycle. You can write this response or draw the cycle.
 * 3)  Briefly detail the nitrogen cycle. You can write this response or draw the cycle.
 * 4)  What is the difference between nitrification, denitrification, ammonification and nitrogen fixation?
 * 5)  Briefly detail the phosphorus cycle – you can write your response or draw a picture.
 * 6)  Imagine you are at the dinner table and are asked to explain what acid rain is and why it is a problem. Write your response here.
 * 7) What is biological magnification and how does it relate to the health warnings given to pregnant women about the consumption of certain fish?
