use the table to answer the questions below.
- for each living or nonliving thing listed in the table, answer the questions across the top of the table. write yes or no in each box for your answers.
living or nonliving thing | gets and uses food? | moves? | grows? | reproduces? | responds to environment? | is it alive?

grass
rock
pine tree
computer
crab
shrub
squirrel
glass
- which things are organisms?
- name one thing that is not an organism. explain why it is not.
critical thinking
choose an organism that is not on the chart. explain how it has all five characteristics of life. write your answer on a separate sheet of paper.
Step1: Recall life - characteristics
Living things get and use food, move, grow, reproduce, and respond to the environment.
Step2: Analyze each item in the table
- Housefly: Gets and uses food (yes), Moves (yes), Grows (yes), Reproduces (yes), Responds to environment (yes), Is alive (yes).
- Grass: Gets and uses food (yes), Moves (some movement like growth - related, yes), Grows (yes), Reproduces (yes), Responds to environment (yes), Is alive (yes).
- Rock: Gets and uses food (no), Moves (no), Grows (no, only physical changes not biological growth), Reproduces (no), Responds to environment (no in a biological sense), Is alive (no).
- Pine tree: Gets and uses food (yes), Moves (some movement like growth - related, yes), Grows (yes), Reproduces (yes), Responds to environment (yes), Is alive (yes).
- Computer: Gets and uses food (no, uses electricity not food in a biological sense), Moves (no, can be moved but not on its own biological power), Grows (no), Reproduces (no), Responds to environment (no in a biological sense), Is alive (no).
- Crab: Gets and uses food (yes), Moves (yes), Grows (yes), Reproduces (yes), Responds to environment (yes), Is alive (yes).
- Shrub: Gets and uses food (yes), Moves (some movement like growth - related, yes), Grows (yes), Reproduces (yes), Responds to environment (yes), Is alive (yes).
- Squirrel: Gets and uses food (yes), Moves (yes), Grows (yes), Reproduces (yes), Responds to environment (yes), Is alive (yes).
- Glass: Gets and uses food (no), Moves (no), Grows (no), Reproduces (no), Responds to environment (no in a biological sense), Is alive (no).
Step3: Answer question 2
Organisms are living things. So housefly, grass, pine tree, crab, shrub, squirrel are organisms.
Step4: Answer question 3
A rock is not an organism. It does not get and use food, move, grow, reproduce, or respond to the environment in a biological sense.

- Housefly, grass, pine tree, crab, shrub, squirrel.
- Rock. It does not exhibit any of the biological characteristics of life such as getting and using food, moving, growing, reproducing, or responding to the environment in a biological way.
