Which one of the following animals may occupy more than one trophic levels in the same ecosystem at the same times?

Options

A. Sparrow
B. Lion
C. Goat
D. Frog

Explanation

To determine which animal may occupy more than one trophic level in the same ecosystem at the same time, we can follow these steps:

### Step 1: Understand Trophic Levels
Trophic levels represent the position of an organism in a food chain. The levels are as follows:
- **Producers** (e.g., plants)
- **Primary Consumers** (herbivores that eat producers)
- **Secondary Consumers** (carnivores that eat primary consumers)
- **Tertiary Consumers** (carnivores that eat secondary consumers)
- **Decomposers** (organisms that break down dead matter)

### Step 2: Analyze the Options
We need to analyze the given options to see which animal can occupy more than one trophic level.

### Step 3: Evaluate the Sparrow
- **Feeding Habits**: The sparrow can feed on seeds and fruits, which places it in the primary consumer category.
- **Additional Feeding**: It also eats insects and worms, which categorizes it as a secondary consumer.

### Step 4: Compare with Other Animals
- **Lion**: Primarily a secondary consumer (carnivore).
- **Goat**: Primarily a primary consumer (herbivore).
- **Frog**: Typically a secondary consumer (eats insects).

### Step 5: Conclusion
The sparrow is the only animal that occupies more than one trophic level at the same time, as it can be both a primary consumer (when eating seeds and fruits) and a secondary consumer (when eating insects).

### Final Answer
The animal that may occupy more than one trophic level in the same ecosystem at the same time is the **sparrow**.
