Question

If organisms are energy deprived (ie given no food, nutrients or light) indoors at 23°C for 24 hours and they

lose mass, what is the m t likely explanation of reduction in mass over those 24 hours?
o Cellular respiration
O Water loss due to evaporation
O Growth and reproduction
The law of conservation of matter

Answer 1

Cellular respiration

Step-by-step explanation:

The likely explanation for this reduction in mass is due to cellular respiration going on within the cell.

• Cellular respiration is a metabolic process in which food materials are broken down to produce energy.
• This is catabolism.
• The food materials contributes significant weight to the body system of an organism
• When the food reserve is depleted, weight loss ensues.
• Cellular respiration will therefore proceed and the food reserve is being depleted.
• This will eventually lead to loss of weight
