All living organisms - plants and animals, respond to their surroundings. We sense our environment through our sense organs. Plants respond to external factors like light, water, temperature, other organisms, pollutants, etc. All organisms, from the prokaryotes to the most complex eukaryotes can sense and respond to environmental cues. Photoperiod affects reproduction in seasonal breeders, both plants, and animals. All organisms handle chemicals entering their bodies. All organisms therefore, are aware of their surroundings. However, human being is the only organism who is aware of himself, i.e., has self-consciousness.
