Actinophryx has an amoeboid body and glassy silica shells. which phylum and class does it belong to

The answer is phylum Sarcodina and class Heliozoa.

Actionophryx belongs to the group of Sarcodina. However, this is an older classification, and it is known that it belong to the groups of amoebas. It has a spherical body (helios, greek for sun) with axopodia (arms) so it is classified to the class sun-animalcules or Heliozoa. The body is surrounded by a glassy silica shell. It lives in freshwater, but some species are found in seas and oceans. 

answer: that would be cheating

explanation:

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.
