Anaerobic bacteria: Bacteria which does not use oxygen or in the absence of oxygen.

since, glycolysis, krebs cycle are essential metabolic pathways in order to produce energy and calvin cycle is essential for the photosynthesis process.
For every 2 people, they would have 1 child. When all the parents die, the population would have 1/2. China had this policy for a while
