Life Needs
	Energy, Environment, Nutrition: -Organisms have basic needs (air, water, food, light (plants)) (K-4) -Organisms die if needs are not met. (K-4) -All animals depend on plants (K-4) -All organism cause changes in their environment (K-4) -Humans depend on natural and constructed environments (K-4) -Patterns of behavior are related to the organism's environment. (K-4) -All organisms must be able to obtain and use resources (5-8) -Regulation involves sensing the internal environment (5-8) -Organisms' behavior evolves through adaptation to its environment (5-8) -The major source of energy of an ecosystem is sunlight. (5-8) -Extinction happens when adaptive characteristics are insufficient for survival (5-8) -The number of organisms in an ecosystem depends on the resources available. (5-8) -Atoms and molecules on the earth cycle among living and non-living things. (9-12) -Organisms both cooperate and compete (9-12) -The energy for life primarily derives from the sun. (9-12) -Chemical bonds of food molecules contain energy. (9-12) -Plants capture energy by absorbing light and using it to form strong chemical bonds between atoms of carbon containing molecules.
