They break down organic matter, recycling carbon and nutrients back into the ecosystem.
Bacteria reproduce asexually through , a process where a single cell duplicates its DNA and splits into two identical daughter cells. Under optimal conditions, some species can double their population every 20 minutes. They can also exchange DNA through conjugation , which allows for the rapid spread of traits like antibiotic resistance. 3. Ecological and Industrial Importance bacterium
Scientists use a Gram stain to classify them. Gram-positive bacteria have a thick peptidoglycan layer that retains purple dye, while Gram-negative bacteria have a thinner layer and an outer membrane, appearing pink. They break down organic matter, recycling carbon and
Common forms include cocci (spherical), bacilli (rod-shaped), and spirilla (spiral). They break down organic matter
