Answer:
Explanation:
Most of the organisms that are affected by the change in temperature are poikilothermic animals. The external temperature of their surroundings affects their internal temperature and thus, causes changes in their metabolic activities.
Organisms which can tolerate a wide range of temperatures are called as Eurotherm and the organisms that have a narrow tolerance range of temperatures are called as stenotherms.
As the temperature of water goes 4°C, the density of water decreases. So, this causes a decrease in the buoyancy of the plankton and they tend to sink with increasing temperature of the water.
The reproductive life of the fishes is most commonly affected by the temperature changes. Trout fish reproduces at a temperature of 3 - 14°C. However, when the temperature is above 24°C, it becomes lethal for the fish.
The optimal growth temperature of Carp fish is in between 20 - 30°C.
Many aquatic animals tend to change their colour with changes in the temperature. The animals that are active during the cold season are usually dark in colour.
