DO NOW 1. Why do you think there are different types of plants and animals in different areas of the world? 2. Why are there not the same animals in Canada as there are in Mexico? 3. Why are there not the same types of plants in the rain forest as there are in the desert?
Review of Key Points Key Point #1: All species have a carrying capacity. Including humans. There are only enough resources on Earth to support a LIMITED NUMBER of humans. Key Point #2: In developed (rich) countries, humans have exceeded our carrying capacity because we consume too many resources. Key Point #3: In undeveloped (poor) countries, humans have exceeded their carrying capacity because there are too many people.
2,200 people will die from starvation by the end of today’s class.
Daily Goal Explain and analyze how abiotic and biotic factors interact to create the various ecosystems of North Carolina’s biome.
ECOSYSTEM An ecosystem is all of the organisms (plants, animals, etc.) that live in a place together with the non-living or physical factors. Organism (animal) Organism (plant) Non-living factors
BIOME A biome is a group of ecosystems that have the same climate and similar organisms. Same climate (long term weather patterns) and organisms (plants/animals)= biome
Biotic & Abiotic Factors Biotic and abiotic (living and non-living) factors interact to create different biomes Abiotic Factors: Location (tilt of Earth, seasons) Amount of sunlight Climate Temperature Soil/Nutrients Precipitation (Rainfall)
Temperate Deciduous Forests http://videos.howstuffworks.com/discovery/28109- assignment-discovery-temperate-forest-video.htm http://videos.howstuffworks.com/discovery/28109- assignment-discovery-temperate-forest-video.htm What is the climate of a temperate deciduous forest? What type of plants/vegetation? How do they adapt to the changing seasons? What types of animals? How do they adapt to the changing seasons?
Temperate Deciduous Forest Tilt of Earth’s axis creates seasons Primarily in Eastern half of US, Canada, Europe, parts of Russia, China, & Japan
NC Biome: Temperate Deciduous Forest Four seasons: winter, spring, summer, fall Climate: Temperature: Hot & humid summers & short, mild winters Precipitation: rainfall year-round (wettest in summer months), high mountains receive snow in winter months Soils: most are acidic and lack nutrients Leaching-water filters nutrients through soil
How is biodiversity affected? Plants and animals must develop adaptations to survive through the changing seasons: Trees lose their leaves to adapt to yearly temperature changes; store energy in roots Animals migrate, hibernate and/or have reduced activity during the winter months
NC Biome Brochure 4 Types of Ecosystems Maritime forest Longleaf Pine Savanna Tidal Salt Marsh Spruce-Fir Forest Soils Description of 6 soil types Climate Temperature Precipitation Plant & Animal Biodiversity
Extension: What would happen to a biome classified by cold temperatures if global warming continues? What do you think would happen to the wildlife living in this biome?
Exit Ticket 1. What factors create a biome? 2. North Carolina is classified as what type of biome? 3. How do factors of a biome affect plant and animal biodiversity? 4. What types of adaptations allow plants and animals to survive the changing seasons in NC?
