Quizplus · Accepted Answer

Pioneer species are plants or organisms that are the first to colonize a barren or disturbed ecosystem. They must be able to survive in harsh environmental conditions such as extreme temperatures, limited nutrients, and lack of water. These species are often small in size and have adaptations that allow them to withstand these conditions.
