Why do American alligators lay eggs in a nest?

• A. To attract mates.
• B. To provide warmth for incubation only.
• C. To protect eggs from predators.
• D. To feed on the eggs themselves.

Answer: (C)

Nesting increases offspring survival by reducing the risk to developing eggs. American alligators build a mound of vegetation, mud, and other plant material that serves as both a warmth source and a shield. The warmth helps incubate the eggs, but the most critical benefit is protection: a guarded nest deters many predators and gives the eggs a safer place to develop. The mother often stays nearby, and the nest location is chosen to be harder for predators to access, further increasing the chance that hatchlings survive after emerging. So while heat is necessary to allow the eggs to develop, the nest’s protective function is the primary reason for laying eggs in a nest.
