The limitation of ecological pyramids is

Options

A. it take into account the same species belonging to two or more trophic levels.
B. it assumes a simple food chain that is most common in nature
C. Saprophytes or decomposers occupy the lower level in the pyramid.
D. None of the above

Answer

### Step-by-Step Solution:

1. **Understanding Ecological Pyramids**:
- Ecological pyramids are graphical representations that illustrate the distribution of biomass, energy, or numbers of organisms at each trophic level in an ecosystem. They can be pyramids of numbers, biomass, or energy.

2. **Identifying Limitations**:
- The question asks for the limitations of ecological pyramids. We need to evaluate the given statements to determine which ones correctly reflect the limitations.

3. **Evaluating Each Statement**:
- **Statement 1**: "It takes into account the same species belonging to two or more trophic levels."
- This statement is incorrect. Ecological pyramids do not account for the same species being part of multiple trophic levels. Each species is typically assigned to one trophic level based on its primary role.

- **Statement 2**: "It assumes simple food chains that are most common in nature."
- This statement is also incorrect. Ecological pyramids do not assume that food chains are simple; they often represent complex food webs.

- **Statement 3**: "Saprophytes and Decomposers occupy the lower level in the Pyramid."
- This statement is incorrect as well. Ecological pyramids typically do not include saprophytes and decomposers, even though they play a crucial role in nutrient cycling within ecosystems.

4. **Conclusion**:
- Since all the statements provided in the question are incorrect, the correct answer is "none of the above," which corresponds to option 4.
