The answer is D, for when one tropic level is eaten by the tropic level above it, the tropic level is supporting the higher one. I. E. Rabbits are supported by the grass because rabbits eat the grass. Also, the grass population would be larger than rabbits, the rabbits larger than snakes, so on and so forth, so B is ruled out. B states that each population is larger than the one BEFORE it, but there is no way there would be more rabbits than grass. Also, there are both herbivores and carnivores in the food chain, so A and C are out. The best answer is D.
As pepsin moves into pH range that is no longer highly acidic it works slowly until it becomes inactive because the less acidic the medium is, is the more the pepsin bonds, that is the bonds between the tertiary protein (pepsin is an enzyme), are broken and this cause a shift in the shape of the active site which means it would not be able to accept the substrate for reaction to take place.
