The easiest way would probably be to measure the rate of formation of CO2 in a hermetically sealed chamber, subtract the rate of a similar chamber but without bugs (the substrate might produce some CO2 on it s own by microbial activity) and divide that by the number of mealworms present. Not a simple experiment to do at home, but not completely impossible either. Throw 100 mealworms in a bottle, no substrate, flush the bottle with CO2-free air (made by passing it through a CaOH solution first), then at T=0 use the outflowing air to precipitate CaCO3 in another bottle of CaOH solution, let it run for an hour, and weigh the resulting precipitate of CaCO3 after filtering and drying. Convert moles CaCO3 to CO2, divide result by 100 and you have the production of CO2 by 1 mealworm in an hour.

The rate of respiration is the number of breaths per minute. All you have to do is count either the number of breaths in OR out (not both) in one minute. To get more reliable results, the experiment should be repeated several times.
The respiration rate is your breathing rate and your pulse rate is your heart beat.
The respiration rate is the number of breaths taken in 1 minute.

rate of breathing how many breaths per minute
The rate of respiration is determined by the levels of oxygen and carbon dioxide in the blood. The main controller of the rate of respiration is the brain.
The average ratio of pulse rate to respiration rate is typically around 4:1.

Bromothymol Blue is a pH indicator that changes color in response to acidity levels. During cellular respiration, carbon dioxide is produced, which reacts with water to form carbonic acid, lowering the pH of the solution. By measuring the color change in Bromothymol Blue, you can indirectly assess the rate of cellular respiration: a faster rate of respiration will result in a quicker color change due to increased production of carbon dioxide. Thus, monitoring the color shift provides a visual representation of the cellular respiration rate.
A pig's normal respiration rate is between 20 and 40 breaths per minute. This respiration rate is normal for pigs that are still eating and growing.
