Mira analyzed oxygen and carbon dioxide in inhaled and exhaled air. She found that the percentages of both gases were different in each. What other gas would most likely also have different amounts in inhaled and exhaled air? ozone (O3) hydrogen (H2) water vapor (H2O) sulfur dioxide (SO2).

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.

idk and i also need to know where are those bio brainy acts lol

not always but somethings can be reproduced in a laboratory.
