levels of organization
directions: analyze the model. explain the parts of the model. they are connected.

1. identify the levels of organization for life in the model above.
2. describe the levels of organization. how are they related?

Explanation:

1. Atoms are the smallest unit of non - living matter.
2. Pure hydrogen, carbon, or oxygen are elements and are at the atom level.
3. Life begins at the cell level as cells are the basic unit of life.
4. Organelles are membrane - bound structures inside a cell that perform specific functions.
5. Mitochondria convert chemical energy (glucose) into cellular energy (ATP).
