it

is w 2002 q 38 and the answer is increase, increase

Dude what was the answer in D?. as far as i remember it was of no meaning.. Well simply eutrophication happens when excess of fertilizers is used .. they get into the river .. make algae grow faster , those algae prevent light from reaching plants beneath.. Algae die.. aerobic bacteria come and use up oxygen.. other sea animals die that's it

It

It wasn't asking about food it was asking about sugar or glucose I think (I dont remember) Chloroplasts was the answer for me.

I think it was sensitivity? I'm not sure tho if it were nutrition they would've sucked the water that goes through the sand..

was sensetivity and yes chloroplasts since they carry out photosynthesis and make glucose and oxygen
