A thorny bush is a type of shrub characterized by its sharp, pointed thorns. These thorns serve as a defense mechanism against herbivores, making it difficult for animals to eat the plant. Thorny bushes can be found in various environments, including deserts and savannas, where they often thrive in harsh conditions. Many species of thorny bushes belong to the Acacia or Cactus families. They play important roles in their ecosystems by providing shelter and food for various animals. Additionally, some thorny bushes produce flowers and fruits that attract pollinators, contributing to biodiversity in their habitats.
