Phytoplankton get eaten by Zooplankton and Zooplankton get eaten by Herring but Phyotplankton make their own energy form sunlight so it's a Producer.
It is not a consumer, it is a primry producer
Only if they eat other zooplankton (other consumers). Most likely though, they are eating phytoplankton (producers), which makes them primary consumers.
no because it eats fish which are primary consumers
Consumer
Zooplankton is a consumer because it eats (consumes) other things, e.g: Phytoplankton.
The blue whale is a tertiary consumer, They feed on krill which are tiny crustaceans that feed on phytoplankton (plants). The whales' only natural predator is the orca which would make the orca the top level consumer.
It is not a consumer, it is a primry producer
Krill is not a decomposer it is a primary consumer. Krills like to eat Phytoplankton and Zoo plankton
A producer
Sun or hydrothermal vent produces for the producer (not an animal but still a producer) NOTE: This example is in the ocean Primary Producer: phytoplankton 1st order consumer / Primary Consumer: zoo plankton 2nd order consumer / Secondary Consumer: fish 3rd order consumer / Tertiary Consumer: Seal / Sealion/ Penguin 4th order consumer / Quaternary Consumer: Killer whale / Shark / Polar bear
It is a consumer. It eats grass
Consumer. Barnacles consume phytoplankton by waving their cirri in the water column. They are not photosynthic.
