Will carried out an investigation to answer the following question:
Does a low-oxygen environment change the rate of photosynthesis?
What is the MOST probable explanation that he will develop after completing his investigation?
O Oxygen is a reactant of photosynthesis, so low oxygen levels decrease the rate of photosynthesis
Oxygen supplies the energy that is stored in food molecules, so photosynthesis stops in conditions where oxygen is not
plentiful
The oxygen in the environment limits the rate of photosynthesis, so photosynthesis proceeds faster as oxygen levels
decrease
Oxygen is not required for photosynthesis to occur, so the rate of photosynthesis is unaffected by low oxygen levels
