Worked Solution & Example Answer:Put a tick (✓) in the box next to the equation that shows how the net production of consumers, N, can be calculated where I represents the chemical energy store in ingested food F represents the chemical energy lost to the environment in faeces and urine R represents the respiratory losses to the environment - AQA - A-Level Biology - Question 2 - 2022 - Paper 1
Step 1
N = I − (F + R)
Answer
This equation correctly represents the net production of consumers, N. It indicates that the net production is calculated by taking the chemical energy stored in the ingested food (I) and subtracting both the energy lost in feces (F) and respiratory losses (R). Therefore, this is the correct choice.
