Life Functions

What is growth?

• Process by which organisms increase in size and/or number of cells.

• How an organism maintains homeostasis

• The means by which a living organism uses molecules from its environment.

• Food energy changed to energy used for life processes. The energy in food changes into a usable form of energy.
