Answer
Brief Explanations:
In a food chain, energy transfer between trophic levels is typically about 10% efficient. From producers (using solar energy) to primary consumers, ~10% of energy is transferred, then 10% to secondary, 10% to tertiary, and 10% to quaternary. Calculating the cumulative efficiency: (0.1\times0.1\times0.1\times0.1 = 0.0001 = 0.01%) (from sun - producer - primary - secondary - tertiary - quaternary? Wait, actually, sun to producer (photosynthesis captures ~1% - 2% of solar energy), then producer to primary consumer (10%), primary to secondary (10%), secondary to tertiary (10%), tertiary to quaternary (10%). So total from sun to quaternary: Let's say sun to producer is 1% (0.01), then producer to primary: 0.01×0.1 = 0.001, primary to secondary: 0.001×0.1 = 0.0001, secondary to tertiary: 0.0001×0.1 = 0.00001, tertiary to quaternary: 0.00001×0.1 = 0.000001 = 0.0001%? Wait, maybe my initial breakdown is off. But the key point is that with each trophic level (after producers), energy is ~10% transferred. So from sun to quaternary consumers, the energy that makes it is very low, less than 0.1% (since 0.1% is 0.001, and the actual is often lower, like 0.01% or less). So the statement is True.
