c. Metabolism Living things use ___________________________ to _______________________________,

_______________________________________ and _____________________________________. ____________________________________is the sum of all of the chemical reactions

carried out in an organism. Give examples of metabolism in humans. ___________________________________

__________________________________________________________________________________ The energy used by organisms originally comes from _____________________.

_________________________, ____________________________ and _______________________ capture this solar energy and use it to make molecules in a process called __________________________________________________________.***Draw the chemical equation for photosynthesis:

These molecules then serve as the ___________________________________________or __________________________________________ for other organisms.*** Cellular Respiration – Draw equation

Energy flows from________________________________________________________________________________________________________________________________________________ (food chain pg 346)- show the flow of energy from one organism to another. Draw your own food chain.

What do the arrows indicate? ________________________________________________d. Homeostasis

Homeostasis is the process by which organisms _______________________________________________________________________________________________________________ex.________________________________________________________________________________

List some other examples of homeostasis in humans: _________________________________________________________________________________________________________

e. Heredity Heredity - _______________________________________________________________________

____________________________________________________________ ______________________ - is the basic unit of heredity and coded in molecules

called ___________________________________________ or DNA. Some damage causes genes to change. A ____________________________________

is a change in the DNA. Most are harmful but some may be beneficial. Give an example of a beneficial mutation and explain. ___________________________________________________________________________________________________________________________________________________________________________________________
