Q1 mention briefly how the following animals make adaptations to survive in the extremely cold climates:
1 arctic fox
ARTIC FOX= 1. Short, heavily furred, rounded ears

Phenomenal breeding raten - Females give birth to as many as 25 cubs per yearn - However, most of these do not survive for more than 6 monthsn - Thus, the high birth rate helps to maintain population growthn n 4. Able to remain active at temperatures of around -50 degrees Celsiusn - Remains active without a corresponding increase in metabolic raten - However, mature foxes rarely live for more than a few years in the n harsh arctic climaten
