Earth's Environmental Systems

5. Organisms like bacteria and fungi that break down waste and dead organisms.
6. Fertilizer runoff can cause large algae growth in waterways
10. This can filter through the spheres by lightning, bacteria, or human intervention.
11. Layers of rock and soil that hold groundwater.
12. The process by which water changes from a liquid to a gas or vapor
16. The loss of water from a plant in the form of water vapor.
18. Producer pull carbon dioxide from air and converts it to oxygen.
21. Organisms that eat other organisms to obtain nutrients.
22. These type of boundaries are when plates collide.
25. this sphere consist of all the water on earth.
26. This sphere runs from crust to core.
28. These type of plate boundaries are when plates slide past one another.
29. This sphere consist of all living things

1. This type of feedback loop is where the input and output cancel out or stabilize each other.
2. Water that is falling out of the sky, this could be rain, drizzle, snow, sleet, hail
3. A network of relationships among parts that exchange energy and matter.
4. Farmers often rotate their crops with this in order to "fix" nitrogen in the soil.
7. These type of boundaries are when plates separate.
8. This sphere is the layer of gases around the planet
9. This type of feedback loop drive outcomes towards extreme.
13. These are matter that organimsl require for their life processes.
14. The layer of the geosphere that is very hot and solid rock.
15. The environment gets most of its energy from where?
17. This is released naturally only when rocks are worn down by water or wind.
18. Organisms that produce their own food.
19. This sphere runs from crust to upper mantle.
20. The process where water vapor becomes liquid. It is the reverse of evaporation
23. This respiration is the chemical reverse of photosynthesis.
24. The layer of the geosphere that has cool rock and makes up earth's surface.
27. Ice-covered parts of Earth
