Answer:
2 and 3
Step-by-step explanation:
Just look at a food pyramid and you will see. If there is more fishing of a fish species, that means the population will go down. This means that if the population of fish goes down, the levels in the energy pyramid below the fish will have less predation, since the anything above a level in the food pyramid will eat anything below it. Also, if there's less fish, that means that the higher levels in the pyramid will recieve less energy since there's less fish for them to eat
