Pacific sardines do not obtain energy directly from the sun. Rather, as fish, they derive their energy from the food they consume, namely plankton and other small organisms. In the marine food web, primary producers such as phytoplankton harness solar energy through photosynthesis to produce organic matter. This energy is then transferred to other organisms as they consume these primary producers or other organisms higher up the food chain. Thus, while the sun indirectly plays a vital role in providing energy to Pacific sardines by fueling primary productivity, it does not provide energy to the fish directly.
