Which one of the following statements for pyramid of energy is incorrect, whereas the remaining three are correct?

Options

A. Its base is broad
B. It shows energy content of different trophic level organisms
C. It is inverted in shape
D. It is upright in shape

Answer

To determine which statement about the pyramid of energy is incorrect, let's analyze the characteristics of the pyramid of energy step by step.

### Step-by-Step Solution:

1. **Understanding the Pyramid of Energy**:
- The pyramid of energy illustrates the flow of energy through different trophic levels in an ecosystem. It is always upright, with producers at the base and consumers at higher levels.

2. **Characteristics of the Pyramid**:
- **Broad Base**: The base of the pyramid is broad because it represents the producers (plants), which have the highest energy content and biomass.
- **Energy Transfer**: According to the 10% law, only about 10% of the energy from one trophic level is transferred to the next level. This means that energy decreases as you move up the pyramid.
- **Shape of the Pyramid**: The pyramid of energy is never inverted. It always has a broad base and a narrow top, indicating that energy diminishes at higher trophic levels.

3. **Evaluating the Statements**:
- **Option 1**: The base is broad. (Correct)
- **Option 2**: It shows the energy content of different trophic levels. (Correct)
- **Option 3**: It is inverted in shape. (Incorrect)
- **Option 4**: The energy flow is from producers to consumers. (Correct)

4. **Conclusion**:
- The incorrect statement is that the pyramid of energy is inverted in shape. It is always upright.

### Final Answer:
The incorrect statement regarding the pyramid of energy is that it is inverted in shape.
