Objectives
• Discuss energy flow through different ecosystems
• Trace cycles of Carbon, Nitrogen, and water

Ecosystem
All the energetic interactions and material cycling that link organisms in a community with one another and with their environment

Energy and Production

Laws of Thermodynamics
Energy is not created or destroyed. It changes form and place
When energy changes form some of it is lost as heat

Definitions
Food Chain– series of steps by which energy stored in plants is passed through an ecosystem

Components
• Producers – plants
• Herbivores – convert plant tissue into animal tissue
• Carnivores – eat other animals, levels
• Omnivores – eats both plants and animals
![Page 12: Energy Flow and Matter Cycles adapted by ccps.k12.va.us.](https://reader036.fdocuments.us/reader036/viewer/2022081503/56649ed95503460f94be85e1/html5/thumbnails/12.jpg)
Components
• Scavengers – animals that eat dead plant and animal matter
• Saprophytes – plant and fungi that absorb dead material
• Decomposers – everything is a decomposer

►Compare and Contrast: Water vs. Carbon and Nitrogen vs. Carbon►How are all of these cycles alike?
►How does water, carbon and nitrogen enter into the earth’s atmosphere?
►How does water, carbon and nitrogen leave the earth’s atmosphere?►Where are each of these stored?
►Predict: If fuels are burned and released into the atmosphere, how does carbon dioxide effect plant growth?
►What are 3 forms of water in the water cycle?
