Answer:
instinctive drift.
Explanation:
Instinctive drift refers to an animal's tendency to return to instinctive behaviors that are in conflict with a conditioned response. The animal no longer practices the behaviors that have already been taught but returns to behaviors which are in accordance to their nature. The idea sprang from the two students of B.F. Skinner named Keller Breland and Marian Breland, tried to teach raccoon to place tokens in a piggy bank but the raccoon has fallen into his instinctive actions of dropping the tokens on the ground.
As per the question, Otis returned to its instinctive behavior of eating the flower and therefore reflects instinctive drift.
