Eubacteria play a crucial role in decomposing dead plants and animals, breaking down organic matter and recycling nutrients back into the ecosystem. This decomposition process is essential for maintaining soil health and promoting plant growth. While eubacteria can thrive in various environments, they are not directly involved in producing nuclear power or providing shelter for plants and animals.
