Barnacles create home sites by attaching themselves to whales. This relationship neither harms nor benefits the whales. 

• parasitism
• commensalism
• mutualism

a relationship that occurs when two or more organims of the same species need the same resource at the same time

• competition
• symbiosis
• predation

Remoras are small fish that swim close to or attach themselves to sharks.  Remoras eat small scraps left as the sharks feed and the sharks are unaffected. 

• Competition
• Predation
• Mutualism
• Commensalism

• To prevent any one species from becoming too dominant

• To make sure plants have enough animals to pollinate them

• To ensure that water sources are not depleted
