有冇生物係唔可以對刺激產生反應？

應該沒有。
沒有，
如果任何一種生物缺乏以上6種中的其中一種特徵，那他根本就不是生物。

0. all organisms can respond to stimuli

1. all organisms need food

2. sessile orgs(include sponges, anemones, corals, barnacles, and sea squirts)

3.Infertile (sterile) animals and homosexual animals (Mules, the mixture of a horse and a donkey are sterile at birth and cannot reproduce)

4. all organisms need to breathe

5. all organisms need to excrete

6. all organisms need to grow

All you listed are required in identifying an organism as living or not. None of them can be omitted.

Any organism satisfying all of the seven requirements is classified as living.
