Question

You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.

Answer 1

Step-by-step explanation:

If the temperature increases then that will decrease the sugar but not the ATP and NADPH. So I predict that diuron will inhibit the photosynthesis because if photosystem II is infered with it then photosynthesis wouldn't work.And also, because paraquat will lower the NADPH and sugar but not ATP. Hence Diuron is the only choice left.
