1. Abiotic/ Biotic

2. Abiotic Non living factors in an ecosystem, that an organism depends on.

3. Air Atmosphere – contains Nitrogen 78% Oxygen 21% CO2  O2 in photosynthesis

4. Water Most organisms are 80% water Greater diversity with more water

5. Soil Mixture of sand, silt, clay, and organic substance – source of nutrients Has many layers and may contain living things in it.

6. Sunlight Life requires energy – common source is the sun Sunlight determines season change

7. Temperature 0- 50°C – most desirable temperature Temperature depends on elevation and latitude

8. Climate Weather over time Allows living things a consistent and predictable environment.

9. Biotic The living or once living things in an ecosystem.

10. Dead Things Bones, Sticks, Leaves, Grass, Etc.

11. Living thing cause: Disease

12. Predation - Food

13. Protection

15. Biosphere entire portion of the earth that is inhabited by life.

16. Ecology Study of interactions that occur among organisms and their environment. Eco – Homes Ology – Study of

17. Ecosystem Interaction of living things with their non – living environment.

18. An organism’s home or shelter.

19. 1.Individual - One single organism of a species

20. 2. Population- All the organisms of a species in a specific area

21. 3. Community - All the populations in a specific area

22. 4. Ecosystem- All the living and non living things in an area

23. 5. Biomes - major types of communities and ecosystems that are typical of broad geographic regions

24. 6. Biosphere- Sphere of earth that comprises of all living things

25. Example

27.  Food Web – interconnection of plants and animals  Food Chain –  follow a single path

28.  Autotrophs - make their own food (plants)  Heterotrophs – can’t make their own food (animals)

29.  Producer – food source ( Plants, Bacteria)  Consumer – Eats producers or consumers ( dog, grasshopper, humans)  Decomposers – Breaks down consumers and producers ( Maggots, Mushrooms, Vultures)

30.  Herbivore – Eats plants only (deer, cow)  Carnivore – Eats animals only (lion)  Omnivore – Eats Plants and Animals (bear, humans, birds)
