1. World Biomes There are 7 world biomes: –Try to name as many as you can. –Write down 2 characteristics of the biome as well. HINT: 1. Tropical Rainforest –Characteristics….

2. World Biomes What are they?

3. 1. Tropical Rainforest Facts 1. Lots of rain (80-180 in. year) 2. High constant temp 3. Most biodiversity 4. Low nutrient soil

4. 2. Savanna Facts 1. Low rain fall (35-60 in. year) 2. More temp changes than rainforest

5. 3. Temperate Grassland Facts 1. Nutrient rich soils 2. Seasonal temps 3. Low rain fall

6. 4. Temperate Forests Temperate Rainforest Temperate Deciduous Forest Temperate Pine Forest Green on Map: Deciduous Forest Facts (Deciduous) 1.More rain than grassland (30-100 in. year) 2. Seasonal temps 3. Water unavailable in winter

7. 5. Desert Facts Extremely low Rainfall (less than 10 In. year) 2. Large daily temp fluctuations

8. 6. Taiga Facts 1. Cold and wet

9. 7. Tundra Facts 1.Cold 2.Low rain fall and mostly frozen (less than 10 in. year)

10. (Ecology Cont.) Populations What is a population? –The amount of individuals of one species. Species have different strategies to reproduce and survive 2 types r and k adapted

11. LIFE STRATEGY r STRATEGY –USUALLY SMALL ORGAINSMS –SHORT LIFE SPAN – HIGH DEATH RATE –MANY FAST MATURING OFFSPRING –LITTLE/NO CARE OF OFFSPRING –EARLY IN LIFE REPRODUCTIVE ABILITY

13. STRATEGY CONTINUED K STRATEGY –LARGER ORGANISMS –LONGER LIFE SPAN – LOW DEATH RATE –FEW, SLOW MATURING OFFSPRING –EXTENSIVE PARENTAL CARE –LATE IN LIFE REPRODUCTIVE ABILITY

15. What is a food web? Shows all predation interactions between species in an ecosystem.

16. Population Growth How populations can grow. Two types- Exponential and Logistic

17. Starts small, but grows to a large amount

18. -S shaped -Reaches a carrying capacity

19. Carrying capacity

21. Currently population is exponential Hopefully will become logistical (S shaped) Carrying Capacity?
