Where does 80 percent of Earth's photosynthetic activity happen?

Answer 1

Photosynthesis takes place wherever there plants, algae, or photosynthetic bacteria and sunlight. More than 50% of the total planetary photosynthesis is believed to take place in the oceans where there are massive numbers of photosynthetic plankton, algae and bacteria. Although land based plants are important, they do not do as much photosynthesis as the ocean-based organisms.

Answer 2

Approximately 80% of Earth's photosynthetic activity occurs in the oceans, specifically in phytoplankton that inhabit the sunlit zones of the water column. These microscopic organisms play a crucial role in producing oxygen and capturing carbon dioxide, forming the base of marine food webs and influencing global climate.

Answer 3

The ocean
