Answer:
Parasitism.
Explanation:
Parasitism is an association in which one organism, lives on another, the host, deriving benefit from it and causing harm to it. 
The tapeworm here is a parasite and it lives inside the cat's(host) body where the tapeworm is specialized for its mode of life. It survive and reproduces very well without needing another specie because it is a hermaphrodite. It causes loss or poor development of unwanted organs such as the digestive, sense organs and muscles. Its long flattened body also provides a large surface area for absorption of nutrients too.
 
        
             
        
        
        
Unique or damaging plate edges cause volcanoes. As the more thick plate subducts, it will dissolve at profundity and the water is driven off, will bring down the liquefying purpose of the overlying mantle wedge, this will make a kind of magma. Volcanic Island Arcs are framed at maritime dangerous plate edges. The hot, light magma, is less thick that the encompassing rock so will ascend to the surface, and will gather underneath the plate that hasn't been subducted. It will then, under expanded weight eject under the ocean. More than thousands of a great many years, it will continue emitting, to shape islands.
