Characteristics of Life Chapter 1 All living things must have a way to gain and use energy.  -Producers (autotrophs): Make their own food by acquiring energy and raw materials from the (nonliving) environment  -Consumers (heterotrophs): acquire energy by eating other organisms  Decomposers: heterotrophs that obtain energy form dead or decaying matter. All living things have to reproduce, grow and develop.  Reproduction: the process of passing genetic information from parent to offspring.  Growth: Increase in cell size or amount  Develop: Changes that occurs throughout and individual’s life. Sexual Reproduction  Requires two donors of genetic information Asexual Repro.  Has only one parent as a genetic donor All living things have the ability to evolve  Evolve: Change in the genetic makeup of a group/population over a period of time.  There are important processes needed for evolution: Mutation: change in the DNA. Foundation of evolution. Adaptations: inherited characteristic or behavior that allows an organism to survive and reproduce in the environment. Natural Selection: "Survival of the fittest," difference in the survival and reproduction based on the environment. All living things are organized:  Arrangement of emergent properties, (put things together and get something new).  Divided into different levels: 1 Atoms-> Biosphere Atoms/ Molecules: Shared by both living and non-living things Cell: The smallest unit of life, abl
