1. Day 72 1.1 Sustainability Unit 4: Sustainable Ecosystems

2. ZOO FORMS

3. Easter Islands Discovered in 1722

4. Easter Islands Discovered in 1722 Treeless Island

5. Easter Islands Discovered in 1722 Treeless Island After cutting down all trees, loss of trees led to erosion, no materials for making boats or fishing  population began declining

6. Ecosystem:

7. Ecosystem: all the interacting parts of a biological community and its environment

8. Sustainable ecosystem:

9. Ecosystem: all the interacting parts of a biological community and its environment Sustainable ecosystem: an ecosystem that is capable of withstanding pressure and giving support (it must endure and support)

10. Parts of an Ecosystem Biotic:

11. Parts of an Ecosystem Biotic: the living parts of an ecosystem Abiotic: the non-living parts of an ecosystem

12. Parts of an Ecosystem Biotic: the living parts of an ecosystem Abiotic: the non-living parts of an ecosystem

13. CuPS Biotic InteractionHow It Works For Biotic Interactions

14. CuPS Biotic InteractionHow It Works CompetitionWhen two or more organisms compete for the same resource such as food in the same location at the same time. For Biotic Interactions

15. CuPS Biotic InteractionHow It Works CompetitionWhen two or more organisms compete for the same resource such as food in the same location at the same time. PredationWhen one organism consumes another organism for food. The organism consumed is the prey and the consumer is the predator. For Biotic Interactions

16. CuPS Biotic InteractionHow It Works CompetitionWhen two or more organisms compete for the same resource such as food in the same location at the same time. PredationWhen one organism consumes another organism for food. The organism consumed is the prey and the consumer is the predator. SymbiosisMutually beneficial interaction between members of two different species For Biotic Interactions

17. SNOWL - for Abiotic For Abiotic Interactions

18. SNOWL - for Abiotic For Abiotic Interactions Abiotic Charact- eristic Why it’s ImportantEffects on Sustainability SoilProvides nutrients for plants and a habitat for many micro-organisms Top layers contain nutrients, can be washed away if there is heavy rain or if trees cut down

19. SNOWL - for Abiotic For Abiotic Interactions Abiotic Charact- eristic Why it’s ImportantEffects on Sustainability SoilProvides nutrients for plants and a habitat for many micro-organisms Top layers contain nutrients, can be washed away if there is heavy rain or if trees cut down NutrientsNeeded for growth, plants and animals need nitrogen and phosphorous Nutrient levels can become unbalanced due to human activities

23. Cycling of Matter and Earth’s Spheres

24. Lithosphere: the hard part of Earth’s surface

25. Cycling of Matter and Earth’s Spheres Lithosphere: the hard part of Earth’s surface Hydrosphere: all the water found on Earth, including lakes oceans and ground water

26. Cycling of Matter and Earth’s Spheres Lithosphere: the hard part of Earth’s surface Hydrosphere: all the water found on Earth, including lakes oceans and ground water Atmosphere: the layer of gases above Earth’s surface

27. Cycling of Matter and Earth’s Spheres Lithosphere: the hard part of Earth’s surface Hydrosphere: all the water found on Earth, including lakes oceans and ground water Atmosphere: the layer of gases above Earth’s surface Biosphere: the regions of Earth where living organisms exist

28. Nutrients:

29. Nutrients: a chemical that is essential to living things and is cycled through ecosystems

30. 4 Types of Nutrient Cycles Water Cycle Carbon Cycle Nitrogen Cycle Phosphorous Cycle

31. The Water Cycle: the most vital _______ part. Condensation, precipitation, evaporation abiotic

32. The Water Cycle: the most vital abiotic part. Condensation, precipitation, evaporation abiotic

33. The Carbon Cycle

34. Like water, carbon moves through Earth’s spheres. Carbon dioxide, a gas, moves from atmosphere into the biosphere and back again. CO2 is returned to the atmosphere when humans burn the fossil fuels for energy

35. The Nitrogen Cycle

36. Nitrogen: 78% of atmosphere

37. Terrestrial Ecosystem: a land-based ecosystem Aquatic Ecosystem: a water-based, either fresh water or salt water, ecosystem

38. The Phosphorus Cycle

39. The Phosphorous Cycle Phosphorous is stored in the lithosphere (rocks and in sediment on ocean floor) Humans mine for phosphate rock  used to make fertilizers and detergents Phosphate is absorbed by plants through roots As decomposers, bacteria break down dead organisms, releasing phosphate back into soil
