Increase
Explanation:
The predator is a type of animal or bird species which kill other animals to obtain its food. The prey is the animal which is killed by the predator. According to the given situation, if the predator species A is eliminated, the population of the predator B will likely increase because there will be no competition between the two species for the same prey. And the chances of predator B obtaining the prey will increase. Hence, the population will increase.
 
        
                    
             
        
        
        
Answer:
This suggests that the moustache is a releaser for aggression.
Explanation:
<em>Fixed action patterns</em> are instinctive programmed responses in different species that are triggered by a specific external sensory stimulus. These stimuli are called sign stimuli or releaser. When the sign occurs, the animal starts a sequence of acts in response to the stimulus and continuous until the series of actions is completed.
The black feathers resembling a mustache in a <em>Northern flickers</em> male are an external sensory stimulus. This trait that can provoke another male to respond aggressively, as a f<em>ixed action pattern</em>.  
This trait might be considered as an <em>unconditioned stimulus</em>, which <em>provokes an unlearned or reflex reaction</em>. These aggressive responses are triggered by reflex.
