Hello.
00:01
So let's answer now the question.
00:02
So in this question we are asked which of the following is true about the condition or phenomenon called eutrophication.
00:15
Now when we speak of eutrophication, it is an ecological problem.
00:22
So it is an ecological problem.
00:27
And it is a process where the water body like lakes or river become reached with nutrients.
00:41
So when the water has had.
00:43
High nutrients or it has an increased nutrients, it suddenly become rich in nutrients.
00:51
This excessive nutrients will cause the algal bloom.
00:57
So the algae will grow rapidly and it is a termed as algal bloom.
01:05
And this algal bloom is somehow dangerous because algal bloom eventually when the algae die or when the algae die, what will happen is it will undergo decomposition and the decomposition process requires oxygen and what will happen, it will cause depletion.
01:28
The algal bloom will cause depletion of dissolved oxygen in the water.
01:36
So dissolved oxygen, okay, it will cause the depletion of dissolved oxygen...
