Question

question 25
fish that eat zooplankton would be considered
primary consumers
detritivores
producers
herbivores
secondary consumers

Explanation:

In a food - chain, producers make their own food through photosynthesis. Zooplankton feed on producers. Fish that eat zooplankton are one step above zooplankton in the food - chain. Primary consumers are organisms that feed on producers. Since zooplankton are primary consumers and the fish eat zooplankton, these fish are secondary consumers. Detritivores feed on dead organic matter, producers make their own food, and herbivores feed on plants.

Answer:

secondary consumers
