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