In ocean ecosystems, phytoplankton act as the primary producers of organic carbon. They convert sunlight and nutrients into organic matter, which serves as the foundation of the food web [^1^]. Their ability to produce biomass by converting inorganic compounds into organic ones is crucial for the survival of animals in the food web.
Essential for oxygen production
Phytoplankton play a crucial role in producing oxygen through photosynthesis, sustaining not only aquatic animals but also those on land. In fact, they produce more than 50% of the world’s oxygen [^3^]. Without phytoplankton, the oxygen levels in our atmosphere would be significantly reduced.
Supporting smaller and larger organisms
Phytoplankton serve as the first step in the marine food chain, providing food for smaller sea organisms such as zooplankton. These zooplankton, in turn, become food for larger marine animals like fish, whales, and even humans [^3^]. Thus, the abundance and health of phytoplankton directly affect the entire food web and the sustainability of marine life.
Aiding the carbon cycle
Phytoplankton contribute to the global carbon cycle by absorbing carbon dioxide from the atmosphere and converting it into organic matter. This carbon is then passed through the food chain as animals consume phytoplankton or other organisms that have consumed them [^4^]. By sequestering carbon, phytoplankton help mitigate climate change.
Key Takeaways:
- Phytoplankton are autotrophic organisms that form the foundation of marine food webs.
- They produce organic matter through photosynthesis, supporting other marine life.
