Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments

GBR or Great Barrier Reef is the largest coral reef, which includes many marine organisms and corals. The GBR water is inhibiting the growth of algae mostly due to Diuron.

Diuron is an unmanageable pesticide found in the GBR. Diuron is highly toxic, persistent, and can travel long paths. Diuron interferes with photosystem II by blocking the electron transfer. PSII is an important membrane protein complex, which plays a crucial role in oxygenic photosynthesis. Thus, any interference in PSII will interfere with the production of NADPH and ATP.

However, the high temperature and paraquat can affect algae in the following ways:

Light energy.

Explanation:

Light energy cannot reach the chloroplasts, preventing ATP, NADPH and sugars because light energy is responsible for photosynthesis in algae. if light energy is not available to algae, then no photosynthesis happens and as a result no energy produced in the form of ATP, NADPH and sugars in the body of algae. so we can conclude that light energy is responsible for the preventing of production of ATP, NADPH and sugars.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
