Does Neptune living things on it

No

Explanation:

Neptune, like the other gas giants in our solar system, doesn't have much of a solid surface to live on and thus humans or any animals species we know of can live there. Hope this helps and have a nice day! :)

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.

it would lead to upper respiratory infections and pneumonia.
