Life Activity:
occurs inside each cell, cells add O2 to food to get the chemical energy out of the food |
|
|
Life Activity
Transport |
Life Activity:
How an organism moves materials (food, oxygen,CO2) around inside its body (to and away from its cells). |
|
|
Life Activity
Locomotion |

|
9. asexual reproduction
|
ONE parent produces offspring that are identical
to the parent (one example is budding) |

3. phylum
|
The Animal kingdom is separated into 9
large groups called? (each of these groups contains animals with similar characteristics) |
|
|
