The given options are:

Correct Answer: Capture energy from sunlight

Fact: Phytoplankton are the autotrophic (self-feeding) components of the plankton community and are a crucial part of ocean and freshwater ecosystems. Yes, phytoplankton thrive in sunshine. Like land-based plants, they contain chlorophyll and need sunlight to grow and prosper. This means phytoplankton must have light from the sun, so they live in the well-lit surface layers of oceans and lakes. Phytoplankton form the base of the marine and freshwater food webs and are critical players in the global carbon cycle. They account for about half of global photosynthetic activity and at least half of the oxygen production, despite amounting to only about 1% of the worldwide plant biomass. Most phytoplankton are too small to be individually seen with the unaided eye.
