1. Biogeochemical cycles
EQ: How do matter and energy move through biological systems?

2. Cycles of Matter
Unlike the one-way flow of energy, matter is recycled within and between ecosystems. - water and carbon cycle

3. What is the Water Cycle?
continuous process by which water moves from Earth’s surface (ground) to the atmosphere and back to the Earth’s surface

4. Water cycle Water enters the atmosphere through: Evaporation
Transpiration

5. Water cycle Water leaves the atmosphere through: Condensation
Precipitation

6. Processes of the Water Cycle
The Sun heats up the water in Earth’s oceans and lakes.

7. Processes of the Water Cycle
1. Evaporation: liquid water changes to a gas (water vapor)

8. Processes of the Water Cycle
2. Transpiration: water vapor is released by plants.

9. Processes of the Water Cycle
3. Condensation: Water vapor changes back into liquid, forming clouds. 
Water vapor in the air gets cold and changes back into liquid, forming clouds. 

10. Processes of the Water Cycle
4. Precipitation:
Water vapor condenses and heavy droplets fall as rain, snow, sleet, or hail

11. The precipitation that falls on the land will soak into the soil and become groundwater or run off the land, flowing back into the ocean to occur again.

12. The Carbon Cycle
carbon is present in the atmosphere as carbon dioxide (CO2)
This carbon dioxide came from
Feeding
Cellular Respiration
Burning of fossil fuels
Decomposition of organic matter

13. CARBON CYCLE SUMMARY: 1. Consumers take in carbon when they eat.
2. Consumers release carbon into the atmosphere during cell respiration.
3. Producers take in carbon during photosynthesis.
4. Decomposers release carbon into the soil through decomposition.
5. Humans release CO2 in the atmosphere when burning fossil fuels.

20. Question 5
The diagram below represents the carbon cycle in a simple form. Arrows show the direction in which carbon moves through the cycle. To improve this model of the carbon cycle, where is another important arrow needed? A. From the land to the ocean B. From the atmosphere to the land C. From the Land to the trees D. From the atmosphere to the trees

21. Question 4
Water continuously moves through the water cycle between land, oceans, and the atmosphere. When water evaporates from a puddle on the street, what happens to the water molecules? A. It is in the air as an invisible gas. B. It disappears and no longer exists. C. It immediately moves up to the clouds. D. It breaks up into hydrogen and oxygen atoms.
