(Side note: haha I just finished this for a class today)
Step-by-step explanation:
There are many things to define something as living such as certain properties. There properties might include things such as growth and development, there energy source, response to the environment, there internal balance, and reproduction.
These all have a big role in telling us whether something is living or nonliving. What it means to be living is to have certain characteristics nonliving organisms might not have. Like flowers there energy source would be the sun, they grow with water and the sun, and response to the environment could mean like how some flowers grow towards the sun, flowers reproduce with their seeds. To be living is to have everything working together in the right spots at one time. Like how your different body systems work together to keep you alive. (reminder: live your life to the fullest because everything doesnt last forever :)) )
