For much of human history, knowledge of the ocean and its currents was not recorded for many reasons - most sailors could not write and information was passed orally.. European nations began systematic ocean explorations but kept information secret between the 15. A: Sunlight – Producers require sunlight for photosynthesis. Ocean life is determined by many factors:. B: Temperature – most animals live near the surface where it is warmer. Ocean life is determined by many factors:.
