Answer:

Explanation:

According to this question, there are three trophic levels of organism in a lake as follows: non-native fish, zooplankton, and algae.

This bloom of algal species can be attributed to the lack of zooplanktons, which represented the only herbivorous (plant eaters) organism in that community. Hence, their relatively small population have an unequal effect on the marine community. This means that the small population of zooplanktons caused an imbalance in the community and this is why ZOOPLANKTON is the keystone species in this scenario.
