4 Which statement best explains how salmon obtain and
use matter to support their biological functions?
Salmon use complex, carbon-based molecules
obtained directly from seawater and the
(A
atmosphere to produce other complex
molecules, such as fats.
Salmon use the carbon, hydrogen, and oxygen
B atoms obtained directly from seawater and the
atmosphere to form sugars and proteins.
Salmon break bonds in complex food
molecules to release the carbon, oxygen, and
hydrogen atoms needed for the formation of
other molecules.
Salmon break down carbon, hydrogen, and
Doxygen atoms obtained from food into smaller,
energy-rich elements.

Where does all the water go? according to the environmental protection agency (epa), in a typical wetland environment, 39% of the water is outflow; 46% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (reference: united states environmental protection agency case studies report 832-r-93-005). chloride compounds as residuals from residential areas are a problem for wetlands. suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 60.4; seepage, 73.7; remaining due to evaporation, 26.4; in the water volume, 46.8. (a) compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (round your answer to one decimal place.) mg/l (b) suppose the epa has established an average chlorine compound concentration target of no more than 58 mg/l. does this wetlands system meet the target standard for chlorine compound concentration? yes. the average chlorine compound concentration (mg/l) is too high. yes. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is too high.
