The student would be a primary consumer since they’re a herbivore.
Answer:
Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.
Explanation:
Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.
A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli. This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.
Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)
If the alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.
If the alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.
Answer:
Nitrogen fixing bacteria is a type of beneficial bacteria (Cyanobacteria) which has the ability to fix the atmospheric nitrogen into ammonium and nitrates form. This atmospheric nitrogen cannot used by the plants so these bacteria fixes it. This is a symbiotic association between plants and bacteria in which both gets benefit. This nitrogen used by the plants and produces more vegetation cover which is a food source of herbivores such as rabbit.
