Worked Solution & Example Answer:The diagram shows the flow of biomass through an agricultural food chain - OCR Gateway - GCSE Biology - Question 21 - 2018 - Paper 1
Step 1
Calculate how much biomass is lost between the plants and humans.
Answer
To find the biomass lost between the plants and humans, we need to subtract the biomass of humans from the biomass of plants.
ext{Biomass lost} = ext{Biomass of Plants} - ext{Biomass of Humans}
ext{Biomass lost} = 22,000 ext{ kg} - 200 ext{ kg} = 21,800 ext{ kg}
Thus, the answer is 21,800 kg.
