1 Trees and Forests Review
Science 6

2 Organisms Producers Consumers Decomposers
Does not feed on other organisms Use energy from the sun to make their own food Examples: Grass Consumers Feed on other living organisms Herbivores, carnivores, omnivores Examples: Ants Decomposers Break down dead plant and animal material Living things that reduce the remains of non-living things to add minerals and nutrients to the soil Examples: Mushrooms, earthworms

3 Tree Types Coniferous Deciduous
What makes coniferous different from deciduous? Needles Cones Types? Spruce Deciduous What makes deciduous different from coniferous? Leaves, fruit, flowers, catkins Broad leaves Elm, Birch, Poplar How are coniferous and deciduous the same? Trunk, bark, seeds

4 Tree Growth How can we tell how old a tree is?
How can we tell how much a tree has grown in a year?

5 Environmental Concerns
Effects of cutting down large areas of forested land: More carbon dioxide in the air Less oxygen in the air What is an environmentalist? What is their perspective? What are other perspectives?

6 Nutrient Cycle

7 Leaf Types

8 Leaf Shapes Detoild or triangular

9 Leaf Shapes Linear or lance

10 Leaf Shapes Oval

11 Leaf Shapes Orbicular or round

12 Leaf Shapes Ovate or pinnate

13 Leaf Shapes Cordate or heart

14 Leaf Shapes Needle

15 Leaf Shapes Oblong

16 Leaf Shapes Lobed

17 Leaf Margins

18 Leaf Margins

19 Leaf Margins

20 Leaf Margins

21 Branching Patterns

22 Food Chains Sun  Producer  Consumer (Primary)  Consumer (Secondary)  Consumer (Tertiary)

23 Benefits of Trees Life Support Raw Materials Habitat Recreation
What are other words for logging? Why might people be for deforestation? Why might people be against tree harvesting?

24 Examples of Fungi Mildews, rusts, mushrooms, puffballs, conks, yeasts and molds.

25 Conks: A type of fungus found attached to tree trunks.
They grown like steps or shelves and have growth rings like trees. They look soft, like mushrooms, but are very hard and are firmly attached to the trunk.

26 Lichens Grow on walls, rocks, tree bark, and other places where neither fungus nor algae could exist alone. They grow very slowly. They can withstand extreme heat and cold (but not smoke or fumes).

27 Photosynthesis

28 Three criteria to classify a plant as a tree
1. One self-supporting structure 2. Consists of a woody substance 3. Is a perennial
