Question

Increased loading of nutrients in the water bodies results in the algal bloom. how is it harmful to aquatic life of plants?

Answer 1

this turns to be harmful to the aquatic life of plants as it cuts off air and light source.it deprives the organisms of oxygen.

Answer 2

WHERE IT STARTS:

when the water is more nutritious simultaneously the algal blooms will grow twice or thrice than normal depending upon the amount of nutrition

THE BEGIN OF THE TORTURE:

These algal blooms ultimately cover teh whole surface of water by restricting the penetration of sunlight and they become the ultimate restrictors

HOW IT ALL GETS STARTED:

eventually when aquatic animals take in oxygen it become depleted after certain time thats where the suffocation begins

hence harmful to aquatic animals

DIDNT GET IT STILL :
WANT AN EXAMPLE?
imagine you are held up in a room with limited supply of oxygen when you are there in the room for like one hour you used almost all the oxygen a.....and now there is only carbondioxide rather than O2

you cant breathe now and eventually due to suffocation and choking you die thats what happens in the case of fish

please no offense thats just an example to make it understand even better
