1. Ecology Objectives: How are materials and energy transferred between organisms in an ecosystem? Can I identify biotic and abiotic factors in major biomes?

2. A. Ecology Scientists who study the connections among living things specialize in the science of ECOLOGY. © J Beauchemin 2006

3. B. What is an Organism? Defined as: ANY LIVING THING

4. Example of an organism: A wolf

5. C. HABITAT: The environment where an organism lives.

6. Example: A Wolf’s Habitat would be found in the arctic tundra, plains, savannahs, and mixed forest environments !

7. There are two factors included in every habitat...

8. D. Biotic factors –Living things like...

9. E. Abiotic factors Nonliving things (physical factors) like...

10. Reality Check Objectives: Can I identify biotic and abiotic factors in major biomes?

11. Task Come up with as many biotic and abiotic factors as you can in a forest ecosystem. Challenge: If another group has your word it does not count. Hint: Come up with things other groups will not think of.

12. We can think about the interactions and types of living things by organizing them into groups, smallest to largest.

13. 1. Organism includes only one organism “STANDS ALONE” Example: ONE Pigeon

14. 2. Population includes all members of the same species that live in the same area. Example: all the pigeons in LaVergne

15. THE GROUPS GET BIGGER and BIGGER!!!!!

16. 3. Community Includes all the different species that live in one area. Example: all the pigeons, ants, maple trees, dogs, etc. that live in LaVergne

17. 4. Ecosystem includes both the community and the abiotic factors. –Example: the LaVergne community plus the cars, buildings, rocks, air…

18. 5. Biosphere the part of the Earth where all life exists.

19. Reality Check How are materials and energy transferred between organisms in an ecosystem?

20. 5 LEVELS OF ORGANIZATION This is the way organisms in a habitat are organized!

21. Reality Check How are materials and energy transferred between organisms in an ecosystem? Can I identify biotic and abiotic factors in major biomes?

47. WORD SEARCH TIME

48. Make your own Word search: Include the following words: Biotic Habitat Abiotic Ecology Organism Producer Population Consumer Community Decomposer Ecosystem Food Web Biosphere Food Chain

49. Extra info:

50. Food webs All organisms need FOOD to survive! Food webs show what eats what.

51. Eat or be eaten Here are some important terms that will help you describe interactions in a food web. 1. Producer (autotroph) –can make its own food –forms the base of the food web

52. Mmmmm…delicious. 2. Consumer (heterotroph) –cannot make its own food There are several words that describe consumers… –Prey: the hunted –Predator: the hunter –Herbivore: eats plants –Carnivore: eats animals –Omnivore: eats both plants and animals

53. Hey, you gonna eat that? 3. Decomposer –Breaks down dead organisms –Examples: bacteria, maggots, fungi, worms –Complete the circle of life by returning nutrients to the soil

54. Your mission… Label the organisms on the coloring sheet you don’t know. (use the next slide to help you) Color in the organisms. On the back, WRITE some examples of how the organisms might interact. Use vocabulary words from your notes.
