Write these in your science journals: natural resource 3.1 Human population growth presents challenges. Write these in your science journals: natural resource natural resource population density Any type of matter or energy from Earth’s environment that humans use to meet their needs. CHAPTER RESOURCES KEY CONCEPT SUMMARY

3.1 Human population growth presents challenges. population density natural resource population density population density A measure of the number of organisms that live in a given area; the population density of a city may be given as the number of people living in a square kilometer. CHAPTER RESOURCES KEY CONCEPT SUMMARY

3.3 sustainable Humans are working to protect ecosystems. conservation sustainable sustainable A term that describes the managing of certain natural resources so that they are not harmed or used up; examples include maintaining clean groundwater and protecting topsoil from erosion. CHAPTER RESOURCES KEY CONCEPT SUMMARY

Reforestation the act of planting tree seeds or young trees in an area where there used to be a forest

Photosynthesis

Photosynthesis The sun is the energy source for most producers in ecosystems WRITE THIS IN YOUR JOURNALS: Plants (and other photosynthetic organisms) take water and carbon dioxide from their environment and use energy from the sun to produce sugars

Key Idea Energy is gained through the process of photosynthesis

Formula 6CO2 + 6H2O + Light C6H12O6 + 6O2

Bill Nye: Photosynthesis History of photosynthesis & explanation of what it is: https://www.youtube.com/watch?v=pdgkuT12e14 Photosynthesis Parody Photosynthesis / Respiration Song https://www.youtube.com/watch?v=65qBlnUTO3k

In your group, explain the process of photosynthesis Read pg 14-15 in FOSS Textbook if you need more help

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process uses CO2 and Water and transforms it into Glucose (sugar) which is needed for the plant. Oxygen is released into the air

Photosynthesis and Respiration Photosynthesis and respiration are key processes for the transfer of energy
