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.
Daily Goal
Explain and analyze how abiotic and biotic factors interact to create the various ecosystems of North Carolina’s biome.
Agenda
Warm-Up (10min) Review carrying capacity & population
growth (5min) Biomes & Biodiversity (30min)
Compare & Contrast Table of NC Ecosystems NC Biome Brochure (30min) Exit Ticket (10min)
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 sunlightClimateTemperatureSoil/NutrientsPrecipitation (Rainfall)
Temperate Deciduous Forests 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 ofUS, Canada, Europe, parts ofRussia, 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
Biodiversity: Plants & Animals Plants (Vegetation):
Hardwoods (oak, maple, hickory) Conifers (mostly pines) Shrubs (e.g. blueberries) Grasses & wild flowers
Animals: Mammals: deer, moose, bear, raccoon,
opossum, skunks Predators: fox, bobcat, lynx, wolves,
mountain lions Birds: song birds & waterfowl (some
migrate)
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

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?
