1. Lesson Starter What are quadrats used for?
What sampling technique would be used to sample small bugs that live up a tree?
What errors may you experience when using a pitfall trap and what can we do to prevent them?

2. Learning Intention To consolidate knowledge of sampling techniques
To learn about the different types of competition
To understand why competition occurs

3. Collect pitfall trap and complete page 14 of the notes
Outside Tasks
Collect pitfall trap and complete page 14 of the notes

4. Competition
Collect 3 cards to survive; sit down when you have 3

5. Competition Why did everyone not get 3 cards?
Competition: Animals and plants have to compete for limited resources. The best adapted animals or plants will win and survive

6. Competition Greater when animals are competing for the SAME resources
The more similar the organism- the greater the competition
Between different species (cow and rabbit) – INTERSPECIFIC
Between the same species – INTRASPECIFIC

7. Competition Between organisms when both use same (limited) resource
Animals- food/water/habitat
Red squirrel vs grey squirrel
Plants- light, water, minerals, space
Redwood trees

8. Think, Pair Share
Herbivores that eat a wide range of plants are likely to be more successful than picky eaters-why?

9. Plants and animals compete with each other for the things they need.
The organism that is better adapted will win the competition and survive.
The organism that loses will either die or move to another habitat.
Animals mainly compete for:
Food
Territory
A mate
Plants mainly compete for:
Water/minerals from the soil
Sunlight
