Vocaloid · Answer

we would need to see the graphs to answer this completely, but if humans are harvesting a lot of the small fish, and the predator fish eat the small fish to survive, then we would expect some kind of decrease in the predator population

so, going along with what I said, which graph shows a significant decrease in the predator population?

imurbbygirl12345 · Answer

The first one or both

Vocaloid · Answer

Hm, that’s a good guess, but if the people just keep fishing without stopping we would just expect the population to keep decreasing without returning to previous levels

I’d say the last graph, which sharply decreases without increasing, would be a better fit
