Bear hibernates whereas some species of zooplankton enter diapause to avoid stressful external conditions. How are these two ways different from each other?
Asked by Topperlearning User | 16th Jun, 2014, 04:14: PM
Hibernation is the winter sleep in cold-blooded animals in polar regions. During hibernation, these animals suspend their metabolic activities when the external temperature becomes unfavourable. Diapause is the phenomenon seen in insects during their developmental stages. During diapause, the metabolic activities are suspended due to unfavourable conditions.
