Herbivory is the act of animals eating plants. This behavior is essential for many ecosystems, as it helps control plant populations and promotes biodiversity. Herbivores, such as deer, rabbits, and caterpillars, consume various parts of plants, including leaves, stems, and roots. By doing so, they can obtain the nutrients they need to survive and grow. In turn, plants have developed various adaptations to protect themselves from herbivores. Some plants produce toxins, while others have thorns or tough leaves. This ongoing interaction between herbivores and plants is a crucial part of the food web, influencing the balance of life in many habitats.
