Anybody can give all the options for q15

It's a graph right???

Quite hard to draw it here....

But I remember

Option 2 was number of plants.
Option 3 was about oxygen
Option.4 was about nutrients.

I thought nutrients should increase as fertilizers is nutrients? Option 4 states a decrease in fertiliser. I chose increase in bacteria. please explain. Thank you

After the point of G the water plants in the river start to die. So it's decrease of nutrients.

The only thing I'm unsure is why there was an increase in the graph after a period of time, and that happen to all graphs which bewilders me.
