Why is it important scientists haven’t identified a lokiarchaeota cell yet

Well, scientists are working hard to find out more about cells, so they should know all of the cells. The Lokiarchaeota cell is one of the only ones they have yet to find out stuff about. Scientists also need to know about it, because it is a part of our bodies, and maybe sometimes they can cause infection in the body. Scientists need to know if it could lead to some of the biggest infections ever.

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.
