According to the video, what are the four rules that biologists use to determine if something is living?

Living things need energy, grow and change, reproduce, and respond to the world around them.

Explain why a rock is considered a non-living thing based on the rules discussed in the video.

A rock does not need energy, grow or change, reproduce, or respond to its environment.

The leaf is considered living because it was once part of a living thing (the tree).

A tree is a living thing that doesn't move. It needs energy, grows, reproduces, and responds to the environment (e.g., losing leaves in the fall).

I can classify objects as living or non-living based on their characteristics.

1
Biologists study living things and have found that all living things need energy, grow and change, reproduce, and respond to the world around them.
2
To reproduce means to make more of something, such as animals having babies or plants making seeds.
3
Even though some living things move, like animals, and some non-living things move, like shadows, all living things must follow all of the rules to be considered living.
