Unit 1: Interactions Within Ecosystems Chapter 1: Ecosystems Section 1.2: Abiotic Parts of an Ecosystem (Slide Show #2)

Abiotic Parts of An Ecosystem Introduction (p.16) What do plants need to survive? Are the items you listed considered abiotic or biotic? Explain.

Abiotic Parts of An Ecosystem Introduction (p.16) When you listed the abiotic factors needed by plants to survive, did you consider the amount of each? For example, consider a blueberry plant versus a cactus. Does each of these plants require the same items you mentioned earlier? Do they each require the same amount of each?

Abiotic Parts of An Ecosystem Introduction (p.16) Different plants are adapted to different abiotic conditions. For example, the blueberry plant can survive here in NL, but would it survive in the desert like the cactus? Explain.

Abiotic Parts of An Ecosystem Abiotic Influences (p.17-19) Read the section “Abiotic Influences” given on pages What are the five abiotic factors that affect an organism’s survival? 1. __________________ 2. __________________ 3. __________________ 4. __________________ 5. __________________

Abiotic Parts of An Ecosystem Abiotic Influences (p.17-19) 1. Light and Light Intensity (Sunlight) Plants and algae must have sunlight to survive. Why? Give an example of an organism that can survive without much sunlight. What adaptations does it have to help it survive?

Abiotic Parts of An Ecosystem Abiotic Influences (p.17-19) Temperature Some organisms need warm temperatures to survive while others can survive in very cold temperatures. Can you think of an example of each and explain their adaptations that help them survive? Warm temperature organism: Cold temperature organism:

Abiotic Parts of An Ecosystem Abiotic Influences (p.17-19) Soil What role does soil play in a plant’s survival? What other organisms rely on soil to survive? List 3 abiotic parts of soil.

Abiotic Parts of An Ecosystem Abiotic Influences (p.17-19) Air/Wind Some organisms need to use air/wind to survive. Example: Some organisms must adapt in order to survive in harsh, windy conditions. Example:

Abiotic Parts of An Ecosystem Abiotic Influences (p.17-19) Water As you may already know, water is an abiotic factor that no organism can live without. What are some ways that organisms use and/or need water to survive?

Abiotic Parts of An Ecosystem Abiotic Influences (p.17-19) Choose an organism that lives in NL. Describe how it is influenced by the abiotic factors below: Organism: SunlightTemperatureSoilAir/WindWater

Abiotic Parts of An Ecosystem Core Lab (1-2A): Field Trip to the Schoolyard (p.20) In this lab, you will explore the following question: What abiotic and biotic factors can you observe and measure in your schoolyard ecosystem? See your lab handout for your instructions.

Abiotic Parts of An Ecosystem Check Your Understanding (p.23) Assignment #1 (Part B) Complete the following “Check Your Understanding” questions given below: #3, #4, #5, #8, and #9 The due date will be assigned by your teacher.
