Now you can ask yourself, "how well does the energ
next?" What you want to know is how much energy
next. To do this you will complete a "conversion efficiency" between
this you divide the energy at the higher energy level by the energy at the lower
This gives you a ratio that you can use for comparison, write your answe
thousands place. Complete this for all of your ecosystems.
