Introduction to Marine Algae
Marine algae, diverse and essential, are photosynthetic organisms that significantly impact the world's oxygen and carbon cycles. They range from microscopic phytoplankton to massive kelps.
Oxygen: Algal Contribution
Oxygen: Algal Contribution
Algae, particularly phytoplankton, contribute an astonishing 50-85% of the oxygen in Earth's atmosphere, rivaling terrestrial forests in their role as oxygen producers.
Carbon Sinks in Oceans
Carbon Sinks in Oceans
Through photosynthesis, marine algae absorb large amounts of CO2, acting as major carbon sinks. This process helps mitigate climate change by reducing atmospheric carbon levels.
Algae and Marine Ecosystems
