1. how do you know something is a living organism?

Explanation:

To determine if something is a living organism, we check if it exhibits all the characteristics of life. These include: 1) Cellular Organization: All living things are made up of one or more cells. 2) Reproduction: They can reproduce, either sexually (involving two parents) or asexually (involving one parent). 3) Metabolism: They perform metabolic processes like respiration (to obtain energy) and photosynthesis (in plants to make food). 4) Homeostasis: They maintain a stable internal environment (e.g., body temperature in animals, water balance in cells). 5) Growth and Development: They grow (increase in size or number of cells) and develop (change in form or function over time). 6) Response to Stimuli: They react to changes in their environment (e.g., plants growing towards light, animals moving away from danger). 7) Adaptation through Evolution: Over time, populations of living things adapt to their environment through the process of evolution. An organism must show all these characteristics to be considered living. For example, a rock does not reproduce, grow, or respond to stimuli in a biological way, so it is not living. A dog, however, is made of cells, reproduces, metabolizes food for energy, maintains a stable body temperature, grows from a puppy to an adult, responds to sounds or sights, and its species has adapted over time, so it is a living organism.

Answer:

Something is a living organism if it exhibits all the characteristics of life: cellular organization, reproduction, metabolism, homeostasis, growth and development, response to stimuli, and adaptation through evolution.
