I would say d, based on the fact matter cannot be created nor destroyed
Carbohydrates have alot of fiber and protein,which our bodies can then convert into energy to move about,and do different things.
D = m/V
m = 75g
V = 4 x 4 x 4 = 64 cm^3
d = 75/64 = 1 11/64 g/cm^3
Carrying capacity, or the maximum number of individuals that an environment can sustain over time without destroying or degrading the environment, is determined by a few key factors: food availability, water, and space
