True or false the competitive exclusion principle can lead to adaptation of organisms trying to occupy the same niche.

The answer is TRUE.

Species occupying the same niche will always compete for the same resources. This is why Gause coined the law of competitive exclusion. The species that has the advantage over the other will outcompete the other for resources. The weak species will, therefore, be gradually eliminated from the niche because they will not be able to reach reproductive age.

However, since competition will be disadvantegous for both species, one way that the competing species can coexist stably is by partitioning the environment and occupying different niches.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
