Answer 1

Answer:

Adapting to Extreme Cold

Extremophiles known as psychrophiles are known to survive at these low temperatures. Different species have come up with different ways to survive these cold temperatures. ... Some organisms have adapted to cold environments by forming symbiotic relationships with other organisms.

Answer 2

Answer:

• aestivation:

prolonged torpor or dormancy of an insect, fish, or amphibian during a hot or dry period.

• Snakes, like all reptiles, are cold-blooded (also known as ectothermic). This means they regulate their body temperature by lying in the sun to warm up, or moving into the shade to cool.
• Hibernation is a common response to cold weather from the frogs.
• Snakes conserve energy through a process called brumation, a slowing of their metabolism and the preservation of energy by limiting their movement.
