Critical Questions
What do all living things need to survive?
All living things need to excrete, reproduce, respirate, digest and get food to survive. With out all of these things any organisms wouldn't live.
What are some commonalities and differences among living things?
Chordates and invertebrates differ in many ways. Chordates for example have a spine or a back bone while invertebrates do not. Some invertebrates are simple and other's are very complex.

Chordates also have mammary glands that they use to nourish their young,
