(A) Assertion $(A)$ is correct because regulators (like birds and mammals) maintain homeostasis through physiological processes like thermoregulation and osmoregulation.Reason $(R)$ is also correct because the ability to maintain internal homeostasis is limited; beyond a certain threshold of environmental stress,these organisms cannot maintain their internal environment and may perish or need to migrate.

$A$: Some organisms can maintain internal homeostasis by means of physiological processes and are called 'Regulators'.
$R$: 'Regulators' can maintain internal homeostasis only up to a limit of stressful conditions.
