Plankton forms the primary food source for many marine animals along the Pacific Coast, including fish, whales, and other marine organisms.

Plankton, consisting of tiny organisms such as phytoplankton (plant-like) and zooplankton (animal-like), serves as the foundation of the marine food web along the Pacific Coast. These microscopic organisms are consumed by a wide variety of marine animals, including small fish, which are then eaten by larger predators like whales, seals, and birds. The abundance of plankton in the nutrient-rich waters of the Pacific makes it a crucial food source for many species, supporting the entire ecosystem
