Answer
Earth could support more people if they eat at lower trophic levels because energy transfer between trophic levels is inefficient, with a significant amount of energy lost at each step.
Solution
a
Energy transfer efficiency: Only about 10% of the energy from one trophic level is transferred to the next level
b
Lower trophic levels: Eating at lower trophic levels means consuming plants or plant-based products directly
c
Energy pyramid: The energy pyramid shows that more energy is available at lower trophic levels, which can support a larger population
Key Concept
Trophic level efficiency
Explanation
Eating at lower trophic levels is more efficient in terms of energy use, allowing more food to be available for human consumption and thus supporting a larger population.
