2. b Energy use
3. c the idea that an organism depends on another for survival
4. d any living thing
5. e Homeostasis

5 Multiple Choice Questions

1. Organization
   1. a fact (true statement) based on your observations
   2. cells take in substances and organize them into complex substances
   3. Interdependence
   4. all species produce organisms by combining their genetic information
2. Growth
   1. all living things are composed of cells. In multicellular organisms some cells are specialized to play a specific role
   2. all living things use energy in a process called metabolism which is the sum of all the cell process
   3. all living things maintain a stable internal condition. Multicellular organisms use more than one system for this function
   4. living things grow by the process of cell division (one cell makes two). Cells are produced by cell division and differentiation. This is called development.
3. the process where one cell splits into two cells
   1. Evolution
