Very small zooplankton.
No
They are microzooplankton and a re holoplankton (plankton that stay plankton their whole life) and they are herbivores. They secrete a gelatinous sack to protect them.
well micro means small and it has the word plankton in it so i guess microzooplankton is tinier than normal plankton
In the Arctic, the energy pyramid consists of primary producers like phytoplankton at the base, followed by herbivores like zooplankton and fish, then predators like seals, whales, and polar bears at the top. This pyramid illustrates the flow of energy from producers to consumers in the Arctic ecosystem.
Plankton is broken down into the three trophic level groups listed below.Zooplankton: animals, so they consume oxygen (respiration) in the waterPhytoplankton: plants, so they consume oxygen (respiration) in the water, but they also consume CO2 (during photosynthesis). As a result of the process of photosynthesis (autotrophic organisms) they only appear/live in the water where it reaches the solar light (not in the depth of sea).Bacterioplankton: bacteria and archaea that remineralize organic material.See the related link listed below for more information:
