Biogeochemical cycles
a.

are not essential for life
b.

move through abiotic and biotic regions
c.

are the result of natural disasters
d.

provide the greatest amount of energy for the earth

The correct answer is option b. "move through abiotic and biotic regions".

Explanation:

Biogeochemical cycles is a term used in ecology to describe the different pathways that chemical substances take during its lifetime. Biogeochemical cycles move through abiotic regions such as the lithosphere, atmosphere and hydrosphere; and move through biotic regions, such as the biosphere. One example of biogeochemical cycle is the carbon dioxide cycle. This chemical substances goes into plants and animals in photosynthesis and respiration processes, and also carbon dioxide is a main component of the atmosphere.

the answer is b

Explanation:

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
