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

Options

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

Answer

To solve the question about which organism exchanges gases with the surrounding atmosphere for respiration through the skin, we can analyze each option provided:

1. **Homo sapiens**: This refers to humans, who belong to the class Mammalia. Humans primarily respire through lungs, and they do not rely on skin for gas exchange.

2. **Rana tigrina**: This is the scientific name for the frog, which belongs to the class Amphibia. Frogs have a unique respiratory system that allows them to exchange gases through their skin, in addition to their lungs and gills. This is a key characteristic of amphibians, especially when they are in a moist environment.

3. **Cyticula crameri**: This organism is a type of parrot, which also belongs to the class Aves. Like mammals, birds primarily respire through lungs and do not utilize their skin for gas exchange.

4. **Panthera leo**: This is the scientific name for lions, which are also mammals. Similar to humans, lions respire through lungs and do not use their skin for gas exchange.

Based on this analysis, the only organism from the options given that exchanges gases through the skin is **Rana tigrina**.

**Final Answer**: B. Rana tigrina
