The Disciplinary Core Idea (DCI) in Life Science is "Organisms and Populations." This DCI focuses on how organisms interact with their environment and with other organisms in their population. In order to understand this DCI, students need to be familiar with the basic structure and function of living things, the levels of organization in living systems, and the ways in which energy flows through living systems.
Organisms are able to maintain an internal environment that is different from their external environment. They obtain and use materials and energy. Organisms grow and develop, and reproduce. Individual organisms die, but the species may continue.
A population is a group of organisms of the same species that live in the same area at the same time. Populations interact with their biotic and abiotic surroundings. The size of a population may change over time, depending on the births, deaths, immigration, and emigration that occur.
