A graph titled "Average plant height (cm) vs. Concentration of sodium phosphate (mg/L)" shows an upward-sloping line that reaches a maximum
value and then stays there over the remainder of the graph.
Average plant height (cm) vs.
Concentration of sodium phosphate (mg/L)
Average plant height (cm)
30 20 10 Concentration of sodium
phosphate (mg/l)
What noticeable trend from this graph might be used to make a conclusion?
A. Average plant height is not affected by the concentration of
sodium phosphate.
B. Average plant height increases with an increase in the
concentration of sodium phosphate until the plants reach a
maximum possible height
C. Average plant height causes an increase in the concentration of
sodium phosphate
D. Average plant height is halved every time the concentration of
sodium phosphate is doubled until all of the sodium phosphate
has been used up

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

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
