  • Classify the organisms that belong to the Kingdom Archaea.
  • List the beneficial roles of archaebacteria in the environment.

Everything You'll Have Covered

What are the four main types of archaea?

~ The four main types of archaea include methanogenic, halophilic, thermophilic, and psychrophilic archaea.

Where do methanogenic archaea live and how do they acquire energy?

~ Methanogenic archaea live in swamps, dirty water, and the stomachs of herbivores. They acquire energy by using hydrogen gas to reduce carbon dioxide to methane.

How are archaea beneficial to humans?

~ Archaea are useful to humans as a potential way to produce methane gas, and to digest cellulose to make biofuels. The enzymes from thermophiles are useful to scientists because they can function at high temperatures, and this helps them perform certain kinds of experiments.

How are archaea beneficial to herbivores?

~ In herbivores, archaea play an integral role in aiding with cellulose digestion.
