Explanation:

An obligate aerobe is a microorganism that requires oxygen for cellular respiration and cannot survive without it. This is in contrast to facultative aerobes (can use oxygen but can also grow without it), semi - aerobes (a less common term, not a standard classification like the others), and passive aerobe (not a recognized scientific term in microbiology for oxygen - requirement classification).

Answer:

Obligate aerobe
