35. Question 17 There is more energy at the bottom (producers) than the top since only 10% of the energy get transferred from one level to the next.

36. Question 18 An experiment is set up to determine which color light makes an aquatic plant undergo photosynthesis the fastest. 4 different plants are placed under white, red, blue, and green light while a 5 th is placed in the dark. All oxygen produced by the plant is captured and measured. A) What is the independent variable? B) What is the dependant variable? C) What is the control group?

37. Question 18 A) The independent variable is the thing that you manipulate- color of light. B) the dependant variable is the thing that you measure- amount of oxygen produced C) The control group is the group that does not have the variable- the plant in the dark.
