Amount of inorganic substances present in an ecosystem is _____. Energy flow is a ________feature of ecosystem.

Options

A. Standing crop , structural
B. Standing state, functional
C. Standing crop , functional
D. Standing state , structural

Answer

To solve the question, we need to fill in the blanks regarding the characteristics of an ecosystem. Let's break it down step by step.

### Step-by-Step Solution:

1. **Understanding the First Blank:**
- The question asks for the amount of inorganic substances present in an ecosystem.
- The term that describes the total amount of inorganic nutrients or inorganic matter in an ecosystem is known as the **standing state**.
- Therefore, for the first blank, we fill in **standing state**.

2. **Understanding the Second Blank:**
- The second part of the question refers to energy flow in an ecosystem.
- Energy flow is a continuous process that occurs through different trophic levels (producers, consumers, and decomposers) and is essential for the functioning of the ecosystem.
- Energy flow is considered a **functional** feature of the ecosystem because it describes how energy moves and is utilized by living organisms.
- Thus, for the second blank, we fill in **functional**.

3. **Final Answer:**
- The amount of inorganic substances present in an ecosystem is **standing state**.
- Energy flow is a **functional** feature of the ecosystem.

### Complete Answer:
The amount of inorganic substances present in an ecosystem is **standing state**. Energy flow is a **functional** feature of the ecosystem.
