Key Scientific Processes and Concepts

condensationis when gas loses energy and transforms into a liquid. evaporation is when

a liquid gains energy and transforms into a gas. cellular repiration is the process cells

use to turn food into energy. transpiration is the process of liquid turning into gas

in vegetation. biogeochemical cycles is the movement of elements through the land,

air, water, and life. combustion is the ability to burn.

photosynthesis is the process of organisms changing carbon dioxide and water into sugars and

oxygen. decomposition is the process of biological materials being broken down into

simpler substances. nitrogen fixation is the process of organisms changing sugars and oxygen
