Question

10. Brown pelicans are fish-eating birds. As a result of an El-Nino event, the population of brown pelicans in southern California declines. Which of the following best explains the relationship between the El Nino event and the population decline?

A. Warmer ocean temperatures can cause fish to move to colder water further from pelican nest sites

B. Lower sea surface heights can result in pelican nest sites being isolated too far from their food supply in the ocean

C. The female reproductive tract of birds does not function at the lower water temperatures of El Nino

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

E. Predatory seal population increase dramatically due to decreased rainfall

Answer 1

Warmer ocean temperatures can cause fish to move to colder water farther from pelican nest sites

Step-by-step explanation:

climate change is an important factor that affects the migration of fish from one place to the other. fish is seen to migrate/move from a warm water(heat) to a cold water/region so as to ensure their survival. the activities of man has affect the climate of our environment causing more heat the water bodies.

the gradual rise in the temperature of the ocean is forcing this species to leave their natural habitat.
