The sequence for species through which the organic molecules in community pass is called a

Options

A. Food web
B. Food chain
C. Nutrient cycle
D. Pyramid of energy

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term that describes the sequence of species through which organic molecules pass in a community.

2. **Identifying the Options**: The options provided are:
- Food web
- Food chain
- Nutrient cycle
- Pyramid of energy

3. **Analyzing Each Option**:
- **Food Web**: This refers to a complex network of interconnected food chains. It represents how various food chains in an ecosystem are related but does not specifically denote a linear sequence.
- **Food Chain**: This is a linear sequence of organisms where each organism is eaten by the next in the chain. It specifically describes how organic molecules and energy pass from one organism to another.
- **Nutrient Cycle**: This refers to the movement and transformation of nutrients in an ecosystem. It does not specifically describe a sequence of organisms.
- **Pyramid of Energy**: This represents the energy flow through different trophic levels in an ecosystem but does not indicate a sequence of species.

4. **Selecting the Correct Answer**: Based on the analysis, the food chain is the correct answer because it specifically describes the sequence of species through which organic molecules pass.

5. **Final Answer**: The sequence for species through which the organic molecules in a community pass is called a **Food Chain**.
