Some salamander larvae develop aggressive feeding behavior and cannibalistic jaw morphology only when crowding is high. Which explanation best describes why this environmentally induced behavior could be favored?

Cannibalistic behavior must be learned directly by the predator that eats the larvae.
D
Environmental effects on behavior cannot influence survival or reproduction.
