Options

A. food chain
B. insectivorous plants
C. saprophytes
D. herbivores

Answer

To solve the question "Ecological pyramid does not accommodate all, except," we need to analyze the options provided and understand the concept of an ecological pyramid.

### Step-by-Step Solution:

1. **Understand the Ecological Pyramid**:
- An ecological pyramid is a graphical representation that shows the distribution of biomass, numbers, or energy among different trophic levels in an ecosystem. It typically includes producers, consumers, and decomposers.

2. **Evaluate the Options**:
- **Food Chain**: This is a sequence that shows how energy and nutrients flow through an ecosystem. It is foundational to the ecological pyramid as it illustrates the relationships between different trophic levels. Hence, it is included in the ecological pyramid.

- **Insectivorous Plants**: These are plants that consume insects but primarily serve as primary producers in the ecosystem. They occupy the first trophic level, so they are included in the ecological pyramid.

- **Saprophytes**: These organisms decompose dead and decaying matter. While they play a crucial role in nutrient cycling, they are not represented in the ecological pyramid since they do not fit into the traditional trophic levels.

- **Herbivores**: These are primary consumers that feed on plants and are located at the second trophic level in the ecological pyramid. They are included in the pyramid.

3. **Identify the Correct Answer**:
- Among the options, saprophytes are the only ones that are not represented in the ecological pyramid. Therefore, the answer to the question is **C) Saprophytes**.

### Final Answer:
**C) Saprophytes**
