What are the two most significant factors affecting photosynthesis in the ocean

• Temperature

• Carbon Dioxide

• Nutrients

• Light

Tags

NGSS.MS-LS1-6

In what way can temperature help to increase photosynthesis?

• Temperature does not play a role

• warmer water at the surface is less dense, and keeps phytoplankton near the surface

• Cold water at the surface is more dense and keeps phytoplankton near the surface
