The higher levels in the pyramid will receive more energy.

The higher levels in the pyramid will receive less energy.

The lower levels in the pyramid will have less predation.

The higher levels will receive less energy (because there's less fish to eat for them) and the lower levels will have less predation (because there is less fish to eat them, since it was stated that this fish was a secondary consumer.)
