Can someone tell me what this is? The chapter's name is Active Transport (on my PPT).

Exocytosis

Explanation:

"a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane."  

You can tell because the content is exiting the cell and fusing with the cell membrane.

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.
