Homework:
Page 69 Section Assessment #1-7

2. Today’s Quiz: Limiting Factors Primary Succession Pioneer Species
Secondary Succession
Climax Community
Lichens (mutualism)

3. Limiting Factors
A limiting factor is any biotic or abiotic factor that restricts the existence, numbers, reproduction, or distribution of organisms.
Examples: Sunlight, Climate, Temperature, Water, Nutrients, Fire, Soil, Space, Other organisms

4. Primary Succession Begins in a place without any soil
Sides of volcanoes
Landslides
Flooding
Starts with the arrival of living things such as lichens that do not need soil to survive
Called PIONEER SPECIES

6. Primary Succession
Soil starts to form as lichens and the forces of weather and erosion help break down rocks into smaller pieces
When lichens die, they decompose, adding small amounts of organic matter to the rock to make soil

8. Primary Succession
Simple plants like mosses and ferns can grow in the new soil

9. Primary Succession The simple plants die, adding more organic material
The soil layer thickens, and grasses, wildflowers, and other plants begin to take over

10. Primary Succession
These plants die, and they add more nutrients to the soil
Shrubs and trees can survive now

11. Primary Succession
Insects, small birds, and mammals have begun to move in
What was once bare rock now supports a variety of life

12. Secondary Succession
Begins in a place that already has soil and was once the home of living organisms
Occurs faster and has different pioneer species than primary succession
Example: after forest fires

14. Climax Community
A stable group of plants and animals that is the end result of the succession process
Does not always mean big trees
Grasses in prairies
Cacti in deserts

A biome is a large group of ecosystems that share the same type of climax community
Terrestrial Biomes
Tundra, Taiga, Temperate forest, Grassland/Shrubland, Savanna, Desert, Tropical rain forest, Temperate rain forest, Tropical seasonal forest
