All living things must be able to adapt to their environments in some way in order to survive. As external environments change, like with seasons, the internal conditions of living organisms must change as well. These internal changes allow organisms to maintain temperature, hydration, and overall health. Which of these is the best example of a living thing showing this characteristic?

A) A mother lion nurses her cubs in the safety of a den.
B) A bear's heart rate lowers to conserve energy during winter.
C) A pupa forms around a caterpillar as it morphs into a butterfly.
D) A squirrel collects and stores acorns and nuts in a tree for winter.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
