Brown pelicans eat fish, as a result of El Nino, the population in southern California of brown pelicans as declined. Which of the following best explains the relationship between El Nino event and the population decline?

• Warmer ocean temps can cause fish to move to colder water away from pelican nests

• Lower surface heights can result in nest sites being isolated too far from food supply

• Male pelicans get disoriented due to the lack of moisture and fail to return to the nest with food

• Predatory seal populations increase dramatically due to decreased rainfall
