decomposers
B
producers
C
scavengers
D
nitrogen fixers
Explanation: 

Detailed explanation-1: -Prokaryotes play several roles in the carbon cycle. Decomposing prokaryotes break down dead organic matter and release carbon dioxide through cellular respiration. Photosynthetic prokaryotes remove atmospheric carbon dioxide and fix it into sugars.

Detailed explanation-2: -They help us digest our food, produce crucial nutrients, protect us from pathogenic microbes, and help train our immune system to function correctly. In addition, without prokaryotes we wouldn’t have cheese, bread, wine, beer, and yogurt.

Detailed explanation-3: -Under the harsh environmental conditions of the bog ecosystem, Archaea contribute to the functioning of the ecosystem and vegetation by performing functions involved in nutrient cycling, stress response, and phytohormone biosynthesis and by interacting with both bacteria and their hosts.

Detailed explanation-4: -Archaea and bacteria are classified as prokaryotes because they lack a cellular nucleus.
