To determine which of these things in an environment is a living thing, we can refer to the characteristics of living organisms. These characteristics include the ability to grow, reproduce, obtain and use energy, respond to stimuli, and adapt to the environment.
Out of the options given, only the "fungus (mushroom)" possesses these characteristics and is considered a living thing. Fungi, such as mushrooms, are living organisms that can grow, reproduce through spores, obtain nutrients from their surroundings, respond to stimuli, and adapt to changes in their environment.
