Question

Which statement is most likely correct regarding soil bacteria that inhabit the polar regions of Earth..

1) they do not carry out the process of respiration
2) they contain enzymes that function at a low temperature
3) thay are part of the abiotic resources of that ecosystem
4) they do not reproduce

Answer 1

The statement that is most likely correct regarding soil bacteria that inhabit the polar regions of Earth is they contain enzymes that function at a low temperature.

Option 2

Step-by-step explanation:

Soil inhabited in Polar Regions are unique as they carry permafrost which is a thick sub-surface layer of soil, this layer is in frozen state for portion of the year. Water molecules and soil particles share bond energy, which prevent thin layer of water from freezing in low temperature and microbes manage this way to survive even in long deep freeze of winter.

These microbes also have consumption of organic matter and allow them to release more
`C O_(2)` into atmosphere. Organisms resistant to extreme low temperature are called Psychrophiles, hence found in permanent cold regions like polar and deep sea.
