The graphic representation of interrelationship between plants and animals is

Options

A. ecological niche
B. ecological pyramid
C. trophic level
D. none of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the graphic representation of the interrelationship between plants and animals. This means we are looking for a visual tool that illustrates how plants and animals interact within an ecosystem.

2. **Analyzing the Options**:
- **Option 1: Ecological Niche**: An ecological niche refers to the role or function of an organism within its environment, including its habitat and its interactions with other organisms. However, it does not serve as a graphic representation, so this option is not correct.

- **Option 2: Ecological Pyramid**: An ecological pyramid visually represents the different levels of organisms in an ecosystem, starting with producers (plants) at the base, followed by herbivores, primary carnivores, and so on. This option effectively shows the interrelationship between plants and animals, making it a strong candidate.

- **Option 3: Trophic Level**: Trophic levels indicate the position of an organism in a food chain or food web. While it relates to energy transfer, it does not provide a graphic representation by itself, so this option is also not correct.

3. **Conclusion**: After analyzing all the options, the ecological pyramid is the correct answer as it graphically represents the interrelationship between plants (producers) and animals (consumers) in an ecosystem.

**Final Answer**: The graphic representation of interrelationship between plants and animals is the **Ecological Pyramid**.
