1. From Earth to Atoms The Stuff of Life

2. Biosphere The part of the earth and its atmosphere in which living organisms exist or that is capable of supporting life. This picture illustrates the density of plankton in the ocean and vegetation on land

3. Ecosystem An ecological community together with its environment, (all of the living and non living parts) functioning as a unit.

5. The plants, animals, soil, air and water that interact in an area are all parts of an ecosystem

6. The soil itself is full of life. Bacteria, fungi, plant roots, insects, worms and other invertebrates. Millions of bacteria and fungi cells can be found in a table spoon of soil.

7. Community

8. The community is made up of the populations of all the living things interacting in an area. Community = Ecosystem – non-living stuff

9. Population A group of individuals of the same species living in one area

10. Individual organism A single organism (part of a population.) An Organism is a living thing

11. Other organisms A bacteria, mushroom and a tree are all examples of organisms

12. Cells Organisms are made up of cells Animal CellPlant Cell

13. Some organisms are single celled This is a bacteria cell

14. Organelles Organelles are the small parts of cells that perform different functions. Chloroplasts synthesize energy in plant cells The mitochondria is where glucose is “burned” to release energy to the cell

15. Molecules A molecule is made up of atoms These chlorophyll molecules help capture the sun’s energy in the chloroplasts.

16. This phospholipid molecules makes up an important part of cell membranes

17. Glucose is one of the molecules we use for energy

18. A molecules that helps determine who we are, what we look like

20. Atoms: The smallest unit of an element CarbonNitrogenOxygen Phosphorus

21. Sub atomic Particles Protons, Neutrons and Electrons make up atoms
