HEL An investigation was designed to determine how freshwater fich maintain homeostasis within their environment. It was observed that the concentration of substances in the fichis was much higher than the
concentration of substances in ponds, les, and streams and that freshwater fish are constant flow of water from the environment into the cells
Based on these observations, in what type of environment must these fish live

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.

nucleus

would be most reasonable answer tbh
