It would be B.) ospreys; decomposers

Since ospreys eat nothing but fish, if all of the trout died from a disease, the ospreys wouldn't have anything to eat because all of the fish are dead. This results in a loss of energy for the ospreys.

However, decomposers would gain more energy because they gain their energy from dead creatures, in this case, it would be the trout.

                       dominant  over blue allele (y).
