Science Operation Manual

In science I’m making Operation manual. There are 4 rules so far.

1. We’re all in this together

2. Everything is connected to everything else

3. All populations have a limit

4. There is no such place as away

I’m going to explain number 2. Plants connect to Animals and Humans. Plants need carbon dioxide so they can breathe out oxygen. Animals and humans need Oxygen to breathe out carbon dioxide. Plants and Animals are both food for humans. Plants are food for Animals.
