John Martin's theory involved the supply of what to phytoplankton?
Light
Freshwater
Iron
Carbon dioxide
Answer
Iron, the crucial element supplied by John Martin's revolutionary theory, acts as a micronutrient essential for the growth and proliferation of phytoplankton, the microscopic algae that form the foundation of the marine food web. Without adequate iron, these tiny organisms struggle to photosynthesize and multiply, limiting the transfer of energy up the food chain and impacting the entire marine ecosystem.
