planktonic food web

The planktonic food web involves tiny organisms floating in water that form the base of aquatic ecosystems. Phytoplankton are microscopic plants that perform photosynthesis, creating energy from sunlight. Zooplankton are small animals that eat phytoplankton. Larger fish and marine creatures then feed on zooplankton, passing energy up the food chain. This web sustains many ocean species and plays a crucial role in controlling carbon dioxide levels, as phytoplankton absorb CO₂. Overall, planktonic organisms form the foundation of oceanic life, supporting diverse ecosystems and influencing global climate.
