Answer

Answer:

competition among individuals for available food sources

Brief Explanations:

Las variaciones en el pico de aves, como en el caso de las aves de Darwin, se deben a la adaptación para acceder a diferentes fuentes de alimento. La competencia por los alimentos disponibles selecciona fenotipos que les permiten sobrevivir y reproducirse, lo que lleva a la variación observada.
