The euphotic zone is characterized by ample sunlight penetration, which allows for photosynthesis to occur effectively. In this zone, light is sufficient to support the growth of phytoplankton and aquatic plants, establishing a vital base for the food web. This abundant sunlight is crucial for these organisms, which use photosynthesis to convert light energy into chemical energy, forming the foundation of many aquatic ecosystems.

In contrast, other zones like the littoral zone, while they might receive sunlight, are more focused on the shallow areas near the shore and are influenced by land-based processes. The limnetic zone pertains more to the open water away from the shore, which can still benefit from sunlight but may not be as directly associated with the significant photosynthetic activity found in the euphotic zone. The aphotic zone, on the other hand, lacks sufficient light for photosynthesis altogether, emphasizing the euphotic zone's distinct role in supporting life in freshwater biomes.
