1 Core Concepts: 1) All living things share common characteristics and are classified based upon similarities and differences of major physical characteristics. 2) The Earth itself and the life forms on it have evolved over geologic time. 3) The theory of evolution explains how species change over time via the process of natural selection. 4) Inherited traits are passed from parents to offspring in predictable patterns. 5) Many factors affect the flow and quality of water as it moves through the water cycle. 6) A variety of renewable and nonrenewable energy sources are used by people to meet their needs. 7) Living things meet their needs through interactions with the biotic and abiotic components in a biome. 8) Limiting factors act to influence the types and numbers of living things that can be supported in an ecosystem.
