How do frogs get their energy when they hibernate

From their energy storage-body fat

Explanation:

Frogs (especially terrestrial frogs) survive during the winter by going into the state of hibernation (dormant state). Since the frogs are cold-blooded animals (depend on environmental conditions), they need to find a hidden place (hibernacula) where they can survive unfavorable cold conditions. During these hibernation state, frogs slow down their activities: there is no moving, breathing, not even the heart beating. Frogs use their body fat storage as an energy source. Glucose from the liver is released in the blood and it acts as an antifreeze.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
