1) Humans, animals, and plants all have basic needs for survival including food, water, shelter, and air. 2) Living things undergo various life processes such as breathing, excreting waste, reproduction, and responding to stimuli. Certain behaviors like smoking can disturb these processes. 3) Plants and animals have developed special characteristics and behaviors to protect themselves from dangers in their environments like extreme weather, predators, lack of resources, and more. These protections help ensure species survival.
