Worked Solution & Example Answer:Which process causes the loss of biomass from food chains? A - OCR Gateway - GCSE Biology - Question 3 - 2021 - Paper 1
Step 1
Identify the process causing biomass loss
Answer
Among the processes listed, respiration is the one that leads to the loss of biomass from food chains. During respiration, organisms convert glucose and oxygen into energy, releasing carbon dioxide and water as by-products. This process consumes matter and energy, resulting in a decrease in biomass.
