Answer:

Parasympathetic nervous system

Explanation:

Parasympathetic nervous system (PNS) along with sympathetic nervous system (SNS) makes autonomic nervous system (ANS). ANS controls the functioning of internal processes like digestion rate, heart rate, respiratory rate etc. During a threat or stressful situation SNS is activated. It increases heart rate, respiratory rate and directs blood flow towards peripheral muscles as a part of "fight or flight response". When the situation becomes normal, PNS is activated which restores all the vitals as a part of "rest and digest" mechanism.

Since here Byron almost got into an accident, he was scared a lot due to which his SNS was activated. Eventually when he realized that he is out of danger, his PNS got activated which returned his heart rate and blood pressure to normal levels.

In this case, insect populations are increasing as a result of birds modifiying they migratory behavior due to the presence of discarded food in the landfills. Most likely the increased insect populations will affect the plants population as well, creating a series of events that alter the equilibrium of the ecosystems.
