Here's a breakdown:

* Inherited: Passed down from parents to offspring through genes.

* Instincts: Complex, unlearned, and automatic behaviors essential for survival.

Examples of instincts:

* Birds building nests: This behavior is innate, even if a bird has never seen a nest before.

* Suckling in mammals: Newborn mammals instinctively know to search for and suckle from their mother.

* Migration: Many animals migrate seasonally, following an internal compass and the pull of instinct.

* Hibernation: Some animals enter a state of dormancy during cold winters, triggered by instinctual cues.

Important Notes:

* Learning can influence instincts: While instincts are innate, they can be modified by learning and experience.

* Not all behaviors are instincts: Many behaviors are learned through observation, practice, or conditioning.
