Classification . Answer the following questions in reference to life's diversity. Choose only the most correct answer.

Premises
Multi-celled consumers that are active at least in part of their lives are in this kingdom.
Besides feeding themselves, these multi-celled organisms, serve as food for most other organisms.
In this kingdom, multi-celled organisms digest their food outside of their bodies.
Often found in extreme environments while having no nucleus, this domain is closer genetically to eukarya.
These prokaryotes are able to colonize extreme environments such as hydrothermal vents on the seafloor.
Yeasts belong to this group.
These multi-celled consumers include herbivores and carnivores.
They have no nucleus and are the most numerous organisms on Earth.
In this domain members have a nucleus and numerous membrane-bound organelles.
In this eukaryotic group, members range from single-celled consumers to giant, multi-celled producers.
