Biogenic structures

Biogenic structures are natural formations created by living organisms in the environment. These include features like coral reefs built by corals, crayfish burrows, or stromatolites formed by microorganisms. They reflect biological activity and can influence the shape and composition of landscapes or sediment layers. Studying these structures helps scientists understand how life interacts with and shapes its surroundings over time, revealing key insights into Earth's history, biodiversity, and ecological processes.
