How does the UV-resistant alga Chlamydomonas nivalis contribute to the melting of glaciers?

What will be an ideal response?


Snow is a surprisingly harsh environment with conditions such as low temperature, low nutrient, and high irradiation of UV. Chlamydomonas nivalis is a green alga that owes its red color to a red carotenoid pigment. This pigment protects the chloroplast from intense ultraviolet radiation by absorbing it. It also absorbs heat, which provides the alga with liquid water as the snow melts around it. As a result, Chlamydomonas nivalis photosynthetic activity deepens the sun cups, and accelerates the melting rate of glaciers and snowbanks.
