Which of the following functional groups form symbiotic relationships with Eukaryotes in deep sea environments?
A) dissimilatory iron-oxidizers
B) methanotrophs
C) sulfide-oxidizers
D) methanotrophs and sulfide-oxidizers

Question

Quizplus · Accepted Answer

Both methanotrophs and sulfide-oxidizers can form symbiotic relationships with eukaryotes in deep sea environments. Methanotrophs can use methane as their energy source and provide nutrition to eukaryotes, while sulfide-oxidizers can use hydrogen sulfide and provide eukaryotes with nutrition and protection from toxic sulfide environments. Dissimilatory iron-oxidizers do not typically form symbiotic relationships with eukaryotes in deep sea environments.
