Suri bought a pet fish. what should she consider when deciding where to put the tank? a)it should be in a place with a stable temperature because fish are endotherms. b)it should be placed in a dark area because fish are endotherms. c)it should be in a place with a stable temperature because fish are ectotherms. d)it should be placed in a dark area because fish are ectotherms.

C)It should be in a place with a stable temperature because fish are ectotherms.

Explanation:

Living organisms can be classified into two major groups depending on how they regulate their body temperature. These two groups are: ECTOTHERM and ENDOTHERM. Endothermic animals are also known as warm-blooded animals because they use internal controlled mechanisms to regulate their body temperature i.e. they control their temperature internally. For example, if the environment is cold, they speed up their metabolic activities in order to generate heat. Example of endotherms is humans.

On the other hand, ectotherms are a set of organisms that rely on external source of heat e.g heat from sun, and their body temperature changes in response to the temperature of their environment. Example of organisms under this category are snakes, fishes, amphibians etc.

Hence, in deciding where to put her pet fish, Suri needs to consider the fish's ectothermic nature and place the tank in a place with stable temperature because the fish's physiological functioning is dependent on the stability of the environmental temperature.
