marine archaea

Marine archaea are microscopic microorganisms that live in ocean waters. They belong to a distinct domain of life, separate from bacteria and eukaryotes. These tiny organisms play essential roles in the Earth's ecosystems by helping to recycle nutrients, including producing oxygen and breaking down organic material. Found in environments ranging from deep-sea vents to upper ocean layers, marine archaea are incredibly adaptable and contribute significantly to the global carbon and nitrogen cycles. Despite their small size, they have a big impact on ocean health and climate regulation.
