How does environmental changes affect an organism’s chance of extinction?
Global warming, loss of habitat, over-abundance of creatures not native to an area (algae or jellyfish bloom)

Give two different examples of how living things move.
Varied: legs, wings, flying, swimming, growing in one spot, moving by hitching a ride with other organisms, etc.

What are the two ways scientists classify living things?
Scientists look at:
1. the internal structures (cells and organs)
2. the external structures (what the organism looks like)

Describe Animalia and Plantae.
Animalia--multicellular organisms that feed on living things
Plantae--multicellular organisms that make their own food

Why do living things reproduce? Give one example of a living thing that reproduces, and explain how.
Living things reproduce to form more of the same kind of organism.
Examples: bacteria split into identical cells,
most birds and fish hatch from eggs
mammals give birth to live young
plants develop from seeds or spores
etc.
