1. Unit 1: Interactions Within Ecosystems Chapter 1: Ecosystems Slide Show #1

2. Getting Started…(p.4) Close your eyes and imagine that you are standing in a forest. Now, list at least 5 things that you “see”. Next, describe the local conditions (eg. land features, temperature, etc.) of your forest setting.

3. Getting Started (con’t) We will know identify those parts of your ecosystem as Living or Non-Living. How would you define a living thing? A living thing is something that shows or has shown the signs of life. That is, anything that is either alive or dead is classified as a living thing.

4. Getting Started (con’t) From your thought web, what signs of life do all of the living things have in common? All living things: Grow Reproduce Move Take in or produce food React to things in their environment Have cells Have a special chemical make-up

5. Getting Started (con’t) How would you define a non-living thing? A non-living thing is something that will never show the signs of life. Examples: What is the difference between a rock and a dead rabbit  ? A rock NEVER showed the signs of life and never will. A dead rabbit, however, was once alive and therefore showed the signs of life. To distinguish between these, scientists classify living things as either dead or alive. So, the dead rabbit is actually a living thing!

6. Getting Started (con’t) From your forest list, classify each thing as either living (L) or non-living (NL). Share your results with the class. LivingNon-Living

7. Using your forest lists, describe how the living things interact with each other, the non-living things, and the local conditions. An example is done for you. Living vs. LivingLiving vs. Non- living Living vs. Local Conditions A bird builds a nest in a tree. A bird perches on a rock. Some birds fly south in the winter (too cold).

8. Getting Started (con’t) What we have described is a forest ecosystem. an ecosystem is a group of interacting living and nonliving things.

9. Section 1.1: Types of Ecosystems Read pages 8-9 in your text. An organism is… any living thing. Example: Adaptations are… Inherited characteristics that help organisms survive in their environment. Example: An habitat is.. The particular place that an organism lives. Example:

10. Types of Ecosystems (con’t) Abiotic and Biotic Parts of the Environment (p.8) Biotic Factors are… The living parts of an organism’s environment. Example: Abiotic Factors are… The non-living parts of an organism’s environment. Example:

11. Types of Ecosystems (con’t) Abiotic and Biotic Parts of the Environment (p.8) Identify the biotic and abiotic parts of this pond ecosystem. BioticAbiotic

12. Types of Ecosystems (con’t) Studying Ecosystems (p.9) An ecosystem is not defined by its geographic size; they can be very small (e.g., a rotting log) or very massive (e.g., Atlantic Ocean). Therefore, there are many, many different ecosystems throughout the province, country and world.

13. Types of Ecosystems Examples of ecosystems within Newfoundland and Labrador. Include: (i) ocean and coastline (ii) forest (iii) freshwater (iv) arctic

14. Types of Ecosystems Identify Flora and Fauna that you might find in each type of ecosystem Ocean and Coastline FloraFauna

15. Types of Ecosystems (con’t) Ocean ecosystems

16. Types of Ecosystems (con’t) Coastline Ecosystems

17. Types of Ecosystems Identify Flora and Fauna that you might find in each type of ecosystem Forest FloraFauna

18. Types of Ecosystems (con’t) Forest Ecosystems

19. Types of Ecosystems Identify Flora and Fauna that you might find in each type of ecosystem Freshwater FloraFauna

20. Types of Ecosystems (con’t) Fresh Water

21. Types of Ecosystems Identify Flora and Fauna that you might find in each type of ecosystem Arctic FloraFauna

22. Types of Ecosystems (con’t) Artic Ecosystems

23. Types of Ecosystems (con’t) Ecosystems in Atlantic Canada (p.10-12) Complete the “Reading Check” on p.12. Assignment #1A: Complete the “Check Your Understanding” questions #1, 2, 3, 8, 10 on p.15. Please complete these questions on loose leaf as it must be passed in. Due date will be assigned and posted on our science website.
