Sensing is the process by which organisms detect and respond to stimuli in their environment. This involves specialized organs and systems that gather information about various factors, such as light, sound, temperature, and chemicals. For example, humans use their eyes to sense light and ears to detect sound, allowing them to navigate and interact with the world around them. In addition to humans, many other species have unique sensing abilities. Animals may rely on smell or touch to find food or communicate with each other. Overall, sensing is crucial for survival, helping organisms make decisions based on their surroundings.
