Lasting genetic similarities make the two bears biological sister species, more closely related to one another than to any others. ... But Ursus maritimus has also evolved to match its polar environment, growing a longer snout than brown bears' and larger, paddle-like paws, both of which aid polar bears in hunting seals.
All of these components are reservoirs of carbon. The cycle is usually discussed as four main reservoirs of carbon interconnected by pathways of exchange. The reservoirs are the atmosphere, terrestrial biosphere (usually includes freshwater systems), oceans, and sediments (includes fossil fuels).
Insolation is the amount of solar energy that is incident on the surface of the earth. For the same insolation, water bodies tend to absorb the most heat as water has a high heat capacity and so do grasslands. Areas such as desserts and glaciers do not absorb high amounts of insolation due to which these areas exhibit extreme, inhabitable environments. The order becomes:
The Atlantic Ocean
A marshy wetland
Nevada desert
Polar ice caps
