Answer:

fixed action pattern, key stimulus; key stimulus, fixed action pattern

Explanation:

  • An innate behavior which specific to a species and is highly stereotyped is termed as a fixed action pattern.
  • This behavior occurs due to a neuronal network that is hard-wired in the species and the response is said to be generated following a key stimulus.
  • A key stimulus is the one that generates a fixed action pattern and this is also called a releaser.
  • A key stimulus can be in the form of shape, sound, color, or a combination of these.
  • In this case, the red spot is a stimulus for the chicks which causes them to peck at their parent's bill, and hence, the red spot is a key stimulus, and pecking of the chicks is a fixed action pattern.
  • The parents regurgitate the food only when the chicks peck at their bills, so pecking is a key stimulus for the parents which causes them to regurgitate the food which is a fixed action pattern.
