Question

Factories have been dumping very hot water used for cooling into this lake. The temperature of water in a lake has risen by several degrees.
What will MOST LIKELY happen to the organisms that live in the colder water in the lake?
A) They will die out.
B) They will increase in numbers.
C) They will move to another lake.
D) They will adapt to the new temperature.

Answer 1

The fourth option is the correct one as the aquatic organisms were already adapted to a cooler condition . But suddenly due to pouring of hot water into the lakes from the factories might result in a drastic change in the temperature and thus the fishes and other aquatic organisms cannot survive .  

I hope it helps.

Plz mark it as the brainliest answer .
