The "base" of the food web is typically comprised of producers, mainly plants and phytoplankton, which convert sunlight into energy through photosynthesis. These autotrophic organisms form the foundation for all food chains, supporting various trophic levels, including herbivores and subsequently, carnivores. The health and productivity of the ecosystem depend on these primary producers, as they are essential for converting solar energy into chemical energy available to other organisms. Thus, the role of producers is critical for sustaining life in any ecosystem.
