The Microalgae, which form the base of the food chain in the ocean and capture carbon dioxide from the atmosphere, appear to rely on a unique strategy to cope with global warming.
As the climate change reduces the availability of nutrients in the sea, marine microalgae or eukaryotic phytoplankton fire up a protein called rhodopsin.
It is related to the protein in the human eye responsible for vision in dim light.
This light-responsive protein is helping the microalgae flourish with the help of sunlight in place of traditional chlorophyll.
They may absorb as much light as chlorophyll-based photosynthesis in the sea, which also captures light to generate energy and food.
