Answer: The sun has an arrow leading to the decomposer, the sun should be at the bottom of the pyramid
Step-by-step explanation:
The sun is the ultimate source of energy which provides energy to the producers. The producers use the light energy to synthesize chemical compound.
The energy from the producers are transferred to the primary consumers and from their the energy is transferred to the next levels.
The sun cannot be decomposed by decomposer so the arrow from the sun leading towards the decomposer is not right.
