In General, What is the Primary Ecological Role of Prokaryotes

Question

In general, what is the primary ecological role of prokaryotes?
A) parasitizing eukaryotes, thus causing diseases
B) breaking down organic matter
C) metabolizing materials in extreme environments
D) adding methane to the atmosphere
E) serving as primary producers in terrestrial environments

Accepted Answer

Prokaryotes, especially bacteria, play a crucial role in breaking down organic matter and recycling nutrients in ecosystems. They decompose dead organisms and detritus, releasing nutrients back into the environment, which can then be used by other organisms. Without prokaryotes, organic matter would accumulate and essential elements would be locked up and unavailable for living organisms.
