Question

All living things respond to external stimuli?
Justify this statement with examples.
​

Answer 1

Answer:

All living things respond to external stimuli because we have various receptors and sensory neurons that signal for immediate action as a response to any external stimuli.

Eg: 1. The immediate removal of hand on touching a hot thing.

2. The touch-me-not plant which shrinks on touch by any external thing.

Answer 2

Explanation:

All living things are able to respond to stimuli in the external environment. For example, living things respond to changes in light, heat, sound, and chemical and mechanical contact. To detect stimuli, organisms have means for receiving information, such as eyes, ears, and taste buds.
