1. YOUR AQUATIC AND TERRESTRIAL ECOSYSTEMS 1. TOTAL OF 300 POINTS FOR THIS LAB 2. 200 POINTS ACQUIRED TODAY WITH YOUR PICTURES, 3 TYPED PAGES, FIRST OBSERVATIONS. 3. FINAL 100 POINTS ACQUIRED WITH YOUR REMAINING 9 OBSERVATIONS OF EACH ECOSYSTEM OVER THE NEXT 2 WEEKS.

2. Ecology The term comes from the Greek word “oikos” which means study. Ecology is the study of the interactions of organisms with one another and their physical environment.

3. ECOLOGY QUIZ 1.Why do organisms interact with each other? 2.What is Ecology? 3.Ecology comes from what Greek word? 4. What is an ecosystem? 5.What does abiotic mean? 6.What are 2 different types of ecosystems?

4. Ecosystems A community of organisms and their abiotic environment.

5. Community The organisms that live in a particular place.

6. Habitat The specific physical location of a community. ALBERT EINSTEIN SAID THAT MAN CAN EXIST ONLY FOR ABOUT 4 YEARS WITHOUT BEES ON OUR PLANET. NO BEES – NO POLINATION – NO PLANTS – NO PEOPLE. GUESS WHAT IS DISSAPEARING? NO ONE REALLY KNOWS WHY – POSSIBLY PESTICIDES? GENETIC ENGINEERING? GLOBAL WARMING? SCIENTISTS HAVE DISCOVERED THAT BEES DON’T LIKE TO FLY NEAR CELL PHONES – THE ELECTROMAGNETIC SIGNALS THROW OFF THEIR NAVIGATION….HMMMMMMMM

7. LAB TOMORROW 1.GET HERE AS SOON AS POSSIBLE. 2.GET STARTED IMMEDIATELY 3.GET IN TEAMS OF 4. 4.PREPARE YOUR 2 BOTTLES A. CUT AN AIR HOLE IN THE BOTTOM BOTTLE B.

8. Diversity The measure of the number of species living in a particular ecosystem. Coral reefs are among the world's most diverse ecosystems, long admired for their vibrant beauty. Home to millions of plant and animal species, these reefs are also a natural wonder, vital economical asset, coastal barrier and integral part of the world's oceans. These aspects have both raised awareness of their delicate ecosystems and yielded new and unique medicines. CORAL REEF WEBSITE

9. Producers Organisms that take energy from their surroundings and store it in complex molecules. Almost all are photosynthetic. Examples are plants, bacteria, and algae.

10. Consumers The rest of the organisms that depend on the producers to obtain their energy.

11. Decomposers Organisms that obtain their energy by consuming organic waste and dead bodies.

12. Trophic Level The level assign by ecologists to each organism according to the energy transferring steps that they are away from the sun.

13. Autotrophs Organisms that make their own food such as plants, some bacteria, and algae.

14. Herbivores Organisms in the second trophic level that eat plants.

15. Carnivores Organisms on the third trophic level and above that are flesh eaters.

16. Omnivores Organisms that eat both plants and flesh.

17. Heterotrophs Those organisms beyond the first trophic level that cannot make their own food.

18. Nitrogen Fixation The change of nitrogen gas from the atmosphere into ammonia products which plants can use to produce their proteins.

19. Greenhouse Effect The ability of gases, such as carbon dioxide, to trap the sun’s heat and in doing so warm up the atmosphere.

20. Plankton Microscopic organisms that live near the surface of bodies of water, who have photosynthetic organisms that are the base of aquatic food webs.

21. Biomes Major biological communities that occur over wide areas of land.

22. Tropical Rain Forest Has a warm and moist climate with little variation in either rainfall (100”/yr) or temperature.

23. Savannas Have a hot climate with alternating wet and dry seasons. Annual precipitation fluctuates between 36” – 60”/year.

24. Deserts Very dry and often hot climate with annual precipitation of 8”/year.

25. Temperate Grassland Have a very dry & hot summer with cold winter. Its annual precipitation fluctuates between 4” and 24”/year.

26. Temperate Desciduous Forest Have a climate that is warm during the summer and cool to cold winters. Its annual precipitation is between 30” – 100”.

27. Coniferous Forests Have a cool short summer and long winters with annual precipitation between 8” – 24”.

28. Tundra Its climate is cold with long winters, short summers and an annual precipitation of 10”.
