When hunting disrupts the balance in the food chain by removing all owls, there will be no predators on snakes, leading to their increase in numbers.  Considering the scenario where the number of lost owls (4) is replaced by snakes, compute for energy units following in completing the table below.  Trophic Levels No. Individuals in Each Trophic Level No. of Units Received from Trophic Level Above No. Units Used / Individual  (Resp) No. Units Used in Trophic Level No. Units Remaining & Passed on to Next Trophic Level Mean No. Units Available per Individual in Trophic Level SUN +E = 6             1) Plants 30   2       2) Grasshopper 19   2       3) Frog 12   2       4) Snake 8 + 4 = 12   2       5) Owl 0   2
