Why was the transition from “purple bacteria” to “green bacteria” important for the evolution of complex organisms? Use evidence from the video and the chart in your answer.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
