Answer:
A botfly that lays an egg in the skin of an animal when the larvae hatches from the egg, it burrows deep into the skin. The animal that may become sick from having the larvae under its skin is called Mutualism.
Step-by-step explanation:
The animal is the host while the botfly is the parasite. A mutualism in which one mutualistic partner removes parasites, as well as dead or diseased skin from another, in return receiving a steady supply of food is called Pollination. Nearly all pollination services involve a mutualism that has evolved over millions of years. Another example is reproduction.
