Encouraging the growth (via nutrient fertilization) of photosynthetic protists in marine environments may help reduce global warming because .A) photosynthetic protists would release a lot of oxygen, and fertilizing them would increase levels of oxygen in the atmosphereB) the increased oxygen consumption by large populations of photosynthetic protists will increase photosynthesis in land plantsC) photosynthetic protists fix atmospheric carbon dioxide, decreasing atmospheric carbon dioxide levelsD) photosynthetic protists are primary consumers in many marine food chains

C) photosynthetic protists fix atmospheric carbon dioxide, decreasing atmospheric carbon dioxide levels

Explanation: photosynthetic protists is a process whereby plant get their inutrients by converting sunlight into energy using photosynthesis. This is because photosynthetic protists fix

atmospheric carbon dioxide,

decreasing atmospheric CO2 levels. Some example of photosynthetic protists include phytoplankton and unicellular algae.

The correct answer is C.

Explanation:

The photosynthetic protists are organisms that can be found in the forms of algea, euglena etc. and they contain chlorophyll pigments which are responsible for the photosynthesis process that decreases carbon dioxide and produces oxygen.

The encouragement of photosynthetic protists' growth can help reduce global warming because of their photosynthesis ability that reduces atmospheric carbon dioxide levels.

I hope this answer helps.
