The population of bison in a prairie ecosystem has significantly declined. what will most likely happen to the grass population the bison feeds on? a. the grass population will increase. b. the grass population will decrease. c. the grass population will be wiped out. d. the grass population will remain unchanged.

a. The grass population will increase.

Prairie is a grassland region. It is mostly occupied with large species of grasses and some shrubs are also grown in this region. The bison are large herbivore mammals which looks like ox. These are grazing animals which feed on grasses of Prairie ecosystem.

The decline in the bison population will result in decrease in feeder population or primary consumer in the ecosystem which feed on primary producer that are grasses. This will cause grass population to grow as there is decline in the number in higher trophic level, therefore, the population in lower trophic level will increase. Hence, the grass population will increase.

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.
