Answer:
Because there is less energy at higher trophic levels
Explanation:
- In a food chain that shows the feeding levels of organisms in an ecosystem, energy decreases as you move from the lowest trophic level to the highest trophic level.
- The lowest trophic level consists of producers which have the highest energy as they trap energy directly from the sunlight.
- The energy is lost from one trophic level to the next up to the highest trophic level which has the lowest energy.
- Therefore, organisms at the highest trophic level are fewer in number but large in size.
Answer:

kg is NOT an SI unit, g is the SI unit for mass.
L is NOT an SI unit, m^3 is the SI unit for volume.
Therefore the answer is B.
