plzzz mark the answer brainliest ✌✌✌

Answer 2

1) They are obligate anaerobes, so they live in place without oxygen. Oxygen actually harms them and sometimes kills them.

2) Most have a cell wall ,which offers the cell support,and a rigid structure that protects them. Plants, bacteria and fungi all have cell walls,too ,but archaea have cell walls made from a different materials.

3) They come in two shapes: coccus (plural cocci) , which is circle-shaped , and bacillus which is a rod- shaped.

4) Most consume carbon dioxide and hydrogen and release methane gas.

5) All undergo methanogenesis, or the formation of methane by microbes.

6) They depends upon syntrophy , or when one organism lives off of the products of another organism
