What are the levels of organization
Biosphere Biome Ecosystems Community Population Species
What is the biosphere
Earth
What is a biome
Major regional area made up of distinct plants and animals
What is an ecosystem
Smaller area in biome, more complex
What is a community
Within ecosystem, group of plants and animals that make up ecosystem
What is a population
One species
What is a species
Group of organisms that are similar and able to breed together

18 in world
13 in BC
What is a physical adaptation
Adaptation of body
What is a behavioural adaptation
Adaptation with the way an organism acts
Do individuals evolve
No, the species does
Characteristics of tundra
Temp:-40 to 18
150-160 cm perception
Little to no trees
Permafrost characteristics
Little soil
Not much growing
Polar bears ,Arctic foxes
Boreal forest characteristics
Temp: -40 to 20
45-65 mm a year precipitation (mainly snow)
Temperate forest characteristics
Temp: 5 to 25 Perception: >200cm Large evergreens 4 distinct seasons Large biodiversity Rich soil Most organisms live on forest floor
Temperate grassland characteristics
Temp: -10 to 30
Precipitation: 25 to 200 cm
Flat
Large grassing animals
Tropical grassland characteristics
Temp: 7 to 30
Precipitation: 25 cm
Salty soil and few plants
Plants have lots of adaptations
