They are omnivores and detrivores: they eat phytoplankton (plants), other plankton, and biological waste.
Animal plankton (aka zooplankton) are omnivores. Plant plankton (aka phytoplankton) are not omnivores. They get their nutrients from the sun much in the way plants do.
I'd assume plankton that are kept in a zoo
There are two sorts of plankton, zoo plankton and phytoplankton. Phytoplankton are plants and are producers while zoo plankton are animals that eat other plankton.
Fresh water shrimp feed on plankton smaller than they are. This is, by and large, phytoplankton but may include some zoo plankton, particularly small eggs. Thus they are technically omnivorous.
A barnicle eats zoo plankton! A barnicle eats zoo plankton!
No, Phytoplankton is the smallest form of plankton.
Zoo plankton eat only algae and bacteria.
Plankton is not algae. Plankton eats algae though.
phytoplankton and zoo plankton
No.
Some plankton are omnivores, because they devour both animal and plant matter. Other types of plankton may be strictly herbivores or complete carnivores. Some plankton is none of these, because it is tiny plants, not animals.
