Definitions
• Ecosystem: A community interacting with the non-living parts of its environment.
• Biotic: Living organisms in the environment, such as plants or animals.
• Abiotic: Non-living physical features of the environment, such as soil and water.

Evidence 1: Card Sort
Sort the cards into 3 columns. Record your answers in a table like below:
Biotic Abiotic Unsure (or both/can’t
agree)
![Page 10: Intro to Ecosystems Biotic vs. Abiotic Factors. Biodiversity The variety of organisms a specific environment or on earth](https://reader034.vdocuments.mx/reader034/viewer/2022051515/551b090855034607418b4e94/html5/thumbnails/10.jpg)
Evidence: Sort contd…
• Look at those that are in the unsure column. Why were those confusing?
• Write down the rule that you used to decide if something is biotic or abiotic.

Let’s Practice!
• For each picture, name as many biotic and abiotic factors as you can for each ecosystem
• Where do you think the ecosystem boundaries are? (Where does it begin and end?)

Evidence 2: Courtyard Ecosystem• Your group will be assigned an area in the
courtyard.
• List as many biotic and abiotic factors as you can.
• Write down the boundaries of your assigned ecosystem.
• What are the Inputs? The Outputs?

Analysis Questions
1. You’re on the beach and find a piece of driftwood. Is it biotic or abiotic? Why?
2. Is a patch of lawn an ecosystem? Explain.
3. What are some biotic & abiotic factors that would affect a plant but not a rabbit?
