Why is anaerobic respiration advantageous to some organisms?

Question

a They may live in an environment that is oxygen poor and need to extract energy from their food
b They may live in an environment that is oxygen poor and require alternate nutrient sources
c They may live in an oxygen rich environment and use it to generate ATP
d They may live in an oxygen rich environment and require alternate nutrient sources

Answer 1

The correct answer is:

a They may live in an environment that is oxygen poor and need to extract energy from their food.

Anaerobic respiration allows organisms to generate energy in environments where oxygen is limited or unavailable. This ability enables them to survive and thrive in such conditions, effectively extracting energy from food sources without the need for oxygen.
