A new kitten is added to a home with an established older cat.The older cat hisses and swats at the younger kitten in the kitchen where they are fed.Which term refers to the behaviour of the older cat? 

A)  commensalism 
B)  predation 
C)  mutualism 
D)  competition

The behavior of the older cat, hissing and swatting at the younger kitten, is an example of competition, as the two cats are competing for resources (food). Commensalism refers to a relationship where one species benefits and the other is neither helped nor harmed. Predation refers to one species hunting and killing another for food. Mutualism refers to a relationship where both species benefit. None of these terms accurately describe the behavior of the older cat towards the younger kitten.
