The diagram provided shows the carbon and nitrogen flow through a man-made mussel bed in the ocean. What evidence would support the law of conservation of mass for this ecosystem?

A. A The amount of carbon and nitrogen removed during harvest equals the amount seeded as biomass.
B. B Carbon and nitrogen enter and leave the ecosystem only through man-made processes.
C. C The mass of scavengers, decomposers, and feces equals the mass absorbed from phytoplankton and detritus.
D. D The total amount of carbon and nitrogen entering the ecosystem equals the total amount leaving the ecosystem.

Describe the change in phase and temperature as water moves from the oceans to the atmosphere and then returns to earth again as rain. a) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature decreases b) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature increases c) evaporation : temperature decreases; condensation : temperature decreases; precipitation (rain) : temperature decreases d) evaporation : temperature increases; condensation : temperature increases; precipitation (rain) : temperature decreases
