Answer 1

there could be alot of oxygen there and the ingredients that is needed for it. I don't think factories have anything to do with it. but you can call water board to check it out.

Answer 2

Is this a "hypothetical" question?  A meander is a bend, and along the outside of the bend, the water will be slower an deposit any materials it's carrying - leaves, branches, that sort of thing.  Because these will decay and release nutrients, the algae will grow there because of the calmer water - it won't be washed away as quickly - and abundant nutrients. So the algae would tend to be present in the meander to begin with.

Now for the surroundings - especially if these occur upriver of the meander - can you think of any way that any of these would affect the amount of nutrients in the water or living conditions ( such as temperature) for the algae which could make the algae grow even better than it would have if they weren't present?

Put these two parts together, and you'll have your answer.

Answer 3

maybe the pollution from the factories is polluting the water. Im not toatally positive.
