primary producers

Primary producers are organisms that create their own food using sunlight, water, and carbon dioxide through a process called photosynthesis. They form the foundation of the food chain and include plants, algae, and some bacteria. By converting solar energy into chemical energy, primary producers provide the essential nutrients and energy needed for other organisms, like herbivores and predators, to survive. In ecosystems, they play a crucial role in supporting life and maintaining balance, contributing to oxygen production and carbon capture. Examples include trees, grasses, and phytoplankton in oceans.
