BIOLOGY: : BIOLOGY: Hierarchy of Living Things Levels of Organization : Levels of Organization 1. Molecules
10. Biosphere Molecules : Molecules We study molecules to see fundamental interactions
Lipids Cells : Cells Study life through the smallest, functional, living thing
Specialization Tissues : Tissues Study life through specialization of cells
Epithelial Organs : Organs Study life through specialized unions of tissue
Skin Organ Systems : Organ Systems Study life through the complex workings throughout the body
Integumentary Organisms : Organisms Study life through the complex, specialized workings of an entire living thing
Bacteria Populations : Populations Study life through the interactions of like organisms and their social structures
Group behaviors Community : Community Study life through the interactions of different populations living in proximity
Predation Ecosystem : Ecosystem Study life through the interactions of different communities and resources in a set environment
Succession Biosphere : Biosphere Study life through the interactions of all the ecosystems of the Earth
Migration Why is the Hierarchy important? : Why is the Hierarchy important? Life has emergent properties within each level of organization
Emergent properties are new properties not present in the smaller parts
Ex. Flight is not present in a feather, a bone, a muscle but it is present when they are combined in a bird Why is the Hierarchy important? : Why is the Hierarchy important? Life is interactive
We are learning more and more that what affects the least living thing can have an impact on the greatest.
Ex. DDT Review : Review Can you name the levels of organization within the Observations? Molecules
Biosphere What would be next? : What would be next? If we found life outside our planet, what would be the next level you would suggest?
What about outside our solar system?
