Cell Division

IV.E: Biological Populations Change Over Time

IV.E.1: The student will understand how biological evolution provides a scientific explanation for the fossil record of ancient life forms, as well as for the striking similarities observed among the diverse species of living organisms.

IV.E.1.1: The student will recognize extinction is a common event.

Natural Selection

IV.E.1.2: The student will describe how the fossil record documents the appearance and diversification of many life forms.

IV.F.1.3: The student will explain how the amount of useable energy available to organisms decreases as it passes through a food chain and/or food web.

Food Chain
Forest Ecosystem
Prairie Ecosystem

IV.F.1.4: The student will know that the total amount of matter in a closed system remains the same as it is transferred between organisms and the physical environment even though its location or form changes.
