Question

Based on Grutter's studies, we can conclude that the presence of cleaner fish ________.

1) reduces the parasite load of other fish
2) decreases the abundance of other fish species
3) decreases species diversity
4) increases predation rates

Answer 1

Grutter's studies suggest cleaner fish help reduce the parasite load on other fish, contributing to a healthier aquatic ecosystem without negatively impacting fish abundance or diversity.

Step-by-step explanation:

Based on Grutter's studies, we can conclude that the presence of cleaner fish reduces the parasite load of other fish. The studies highlighted do not indicate that cleaner fish decrease the abundance or diversity of other fish species, nor do they increase predation rates. Instead, the presence of cleaner fish is generally beneficial as it helps to control parasites, which can enhance the growth rate and overall health of fish populations. The cleaner fish provide an essential service by cleaning the parasites off of other fish, leading to a more stable and balanced ecosystem.
