Adaptations of Living Beings

The video discusses how living beings, particularly plants, have developed special adaptations to survive in various environments. These adaptations include structural and behavioral changes that help them cope with stressors like temperature extremes, water scarcity, and predators. Examples include needle-like leaves in snowy areas, water-storing stems in cacti, and large leaves in low-light conditions. Additionally, plants have developed defense mechanisms such as thorns and bitter compounds to deter predators.

What are adaptations in living beings?
