The exchange of gases with the surroundind atmosphere for respiration takes place through the skin in which of the following organisms?

Options

A. Homo sapiens
B. Rana tigrina
C. Psittacula Krameri
D. Panthera leo

Answer

To solve the question regarding which organism exchanges gases with the surrounding atmosphere through the skin, we can follow these steps:

### Step 1: Identify the Organisms
The question provides four options:
1. Homo sapiens (Humans)
2. Rana tigrina (Frogs)
3. Cetacula cremarii (Rose-ringed parakeet)
4. Panthera leo (Lions)

### Step 2: Understand the Respiration Mechanisms
- **Homo sapiens (Humans)**: Humans primarily respire through lungs. They take in oxygen through their nostrils and mouth, which is then processed in the lungs. Humans do not respire through their skin.

- **Rana tigrina (Frogs)**: Frogs are amphibians that have a unique respiratory system. They can respire through their lungs when on land, but they also have the ability to absorb oxygen directly through their moist skin when in water or humid environments. This makes them capable of cutaneous respiration.

- **Cetacula cremarii (Rose-ringed parakeet)**: Parakeets, like other birds, primarily respire through lungs. They do not have the ability to exchange gases through their skin.

- **Panthera leo (Lions)**: Lions, being mammals, also respire primarily through their lungs. They do not utilize their skin for gas exchange.

### Step 3: Determine the Correct Answer
From the analysis above, the only organism that can exchange gases through its skin is **Rana tigrina (Frogs)**. Therefore, the correct answer is:

**Correct Answer: Rana tigrina**
