Physical adaptations are one way plants adjust to specific environmental conditions. For example, cacti have spines in place of leaves to prevent water loss in the arid conditions of the desert. Chemical adaptations are another means for plant protection. Many plants produce toxic or noxious compounds to protect themselves from insects or animals that would eat them, to reduce competition from other plants, or even to change the response of pollinators. Humans often harvest these compounds for their own benefit.
