Describe what happens when cells divide uncontrollably?

Typically when cells divide uncontrollably and spread they form into cancer. A change in DNA causes the cell to begin to act in this manner. A cell could do this from many different causes such as exposure to radiation, harmful chemicals, and smoking.

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.
