They adapt to their environment

3. What are some things that are living:
Birds
Bacteria
Plants
Fungi

4. Once Living/Dead
Once alive, but now physically inactive (no movement, response, reproduction, metabolism, growth)
Still in it’s natural state
Ex: Fallen Tree branch
dried flower
dead squirrel

5. What are some things that are non-living?
Rocks
Wooden table
Plastic
Rubber

6. 1. Made of Cells Unicellular - one cell Multicellular - many cells

Multicellular - many cells
Ex: cats

7. 2. Obtain & Use Energy Autotrophs - make their own food
Ex: all plants
Heterotrophs - must find and eat food
Ex: cows, birds, lizards

It can reproduce, but only in a host cell
Does not have cells
Evolves through natural selection
