Prokaryotes are small, microscopic creatures that include bacteria and archaea.these little animals make up approximately 30% of all aquatic life.They perform an important role in keeping our seas healthy, but new research suggests that climate change could have a significant impact on their balance.
Prokaryotes are some of our planet’s oldest and most resilient life forms. They flourish in a variety of settings, including warm tropical waters and the freezing depths of the polar regions. Prokaryotes are amazingly common, even though they are very small.
There are about two tons of them for every person living today. These bacteria are critical to the ocean’s food system, providing necessary nutrients for fish and other marine species that many people rely on for sustenance.
Prokaryotes are noteworthy for their capacity to grow quickly. When they multiply, they emit huge amounts of carbon, a greenhouse gas that contributes to climate change. It is estimated that these creatures emit approximately 20 billion tonnes of carbon each year from the ocean’s top layers.
Another group of tiny sea creatures, called phytoplankton, uses sunlight and carbon dioxide to make energy, which helps to balance this out. Prokaryotes and phytoplankton work together to absorb much of the carbon dioxide that people emit into the atmosphere.
Climate Change’s Impact on Prokaryotes
As global temperatures rise, scientists are learning more about how climate change may affect the delicate equilibrium of our oceans. Research suggests that while prokaryotes may survive in warmer temperatures, larger marine animals such as fish and plankton may struggle.
Prokaryotes may lose just around 1.5% of their total biomass for every degree Celsius increase in ocean temperature, which is far lower than the estimated 3-5% drop for bigger marine organisms.

If prokaryotes become more prominent in the ocean ecosystem, they may use more nutrients and energy, which fish require to grow and reproduce. This trend may result in fewer fish available to the billions of people worldwide who rely on seafood as their primary source of protein.
Furthermore, research indicates that prokaryotes might produce an additional 800 million tonnes of carbon per degree of heat per year. It is important to note that this is equivalent to the whole amount of carbon emissions that are produced by all of the nations that are members of the European Union combined
If we do not take action, ocean temperatures might rise by 1°C to 3°C by the end of the century. If prokaryotes expand their carbon output as expected, our seas would have a harder time absorbing human-caused carbon emissions. This complicates meeting global targets for lowering greenhouse gas emissions.
Furthermore, falling fish populations might have a significant impact on food security. Approximately 3 billion people worldwide rely on fish for nourishment. If fish stocks continue to fall owing to changes in marine ecosystems, many communities may face starvation and health problems.
