Responding to Stimuli

The video explains how organisms, including humans, animals, and plants, respond to stimuli in their environment. Stimuli are events that affect behavior, prompting responses for survival. Examples include dogs reacting to territorial intrusions, bacteria adapting to environmental changes, plants adjusting to light and water availability, rabbits responding to threats, and birds migrating due to temperature and food availability. Proper responses to stimuli are crucial for survival, while failure to respond can lead to death.
