The answer would be 502 grams because of the law of conservation of mass, you can't create or destroy mass so then 2 grams plus 500 grams is 502. I am 100% positive that B is correct.
The law of conservation of mass says that the mass cannot be created or destroyed. Hence, the 2 grams of the sugars and the 500 grams of the water together as a solution would make a total of 502 grams of the solution. The sugars may not be visible due to dissolving, but the mass of the sugar would still be there in the solution.
Bacteria are decomposers when they are turning the dead material in decaying organisms into nutrients. They become producers when they provide those nutrients for plants.
The loss of phytoplankton is a huge problem for marine food chains, says Worm, because every creature in the ocean either eats phytoplankton or eats other organisms that depend on it.
