What term refers to the first organisms to colonize a newly formed or barren area?

Explanation:
Pioneer species are the first organisms to colonize a newly formed or barren area. They tolerate harsh conditions and initiate soil formation—think of lichens and mosses growing on bare rock. As they live and die, they break down rock and add organic material, creating a thin soil layer that allows other plants to take root. This starts ecological succession and gradually increases habitat complexity and biodiversity over time. Mutualism is about beneficial interactions between species, biodiversity is the variety of life in a place, and extinction is the disappearance of a species.
