(SC.912.L.17.9) A team of ecologists observed feeding patterns of several populations in the desert. The energy pyramid shown below depicts the feeding patterns the ecologists observed. Which of the following best explains the difference in the amount of available energy in the trophic levels of the desert ecosystem?
a)
There is less energy available in the producers because their tissues are less dense than those at higher trophic levels.
