Question

Quizplus · Accepted Answer

Primary productivity is the rate at which energy becomes stored in organic compounds through photosynthesis.

Answer: B
 Dissolved inorganic carbon is the main form of carbon storage in sea water; it is taken up by marine producers and converted to carbon dioxide.

Answer: C
 The straight-line sequence of steps by which chemical bond energy moves to higher trophic levels is called a food chain.

Answer: D
 The amount of energy from autotrophs that is available to first-level consumers is called secondary productivity.

Answer: E
 The movement of a nutrient among environmental reservoirs and into and out of food webs is called a biogeochemical cycle.
