Weather & Climate
Climate?
• A regions year-after-year patterns of temperature &
precipitation.
p. 96
Weather & Climate
How does climate differ from weather?
• Climate = average conditions over long periods of time.
• Weather = daily conditions.
p. 96
There are many factors that
determine global climate.
• Solar energy trapped in the
biosphere.
• Latitude.
• Transport of heat by winds &
ocean currents.
Factors Affecting Climate
There are many factors that determine global climate.
p. 96
Factors Affecting Climate
Solar energy is the light energy from the sun.
Balance between heat gained & heat lost is determined by three
gases (greenhouse gases) in the atmosphere.
• Carbon Dioxide (CO2)
• Water Vapor
• Methane
p. 97
Factors Affecting Climate
Greenhouse Effect:
p. 97
Factors Affecting Climate
Latitude & solar energy.
• Solar energy is most intense at the equator.
p. 97
Factors Affecting Climate
Heat transport in the biosphere.
• Unequal distribution of heat creates winds
& currents.
• Earth’s winds are caused by _________
difference due to heat.

density
Factors Affecting Climate
Heat transport in the biosphere.
• Similar patterns of heating & cooling occur in the oceans.
• Ocean currents transport large amounts of heat.
• Figure 4-3, p. 98

Niche
Tolerance?
• Upper & lower limits of environmental conditions in which &
organisms can survive.
- includes both physical & biological conditions
• Ability to survive & reproduce under a range of environmental
circumstances
• Tolerance for environmental conditions determines habitat
(place an organism lives).
p. 99
Niche
Tolerance:
p. 99
Niche
Niche?
• The range of physical & biological conditions in which a
species lives & the way the species obtains what it needs to
survive & reproduce.
Three aspects of a niche:
• Resources – necessity for life (water, light, food, space)
• Physical Aspects – abiotic (climate, moisture)
• Biological Aspects – biotic (reproduction, food)
p. 99
Competition
How does competition shape communities?
• Competition for limited resources.
• Occur within the same species & among different species.
p. 100
Competition
Competitive Exclusion Principle:
• No two species can occupy the same niche, in the same
habitat, at the same time.
p. 100
Competition
Dividing resources:
• Instead of competing for similar resources species usually
divide them.
• Competition determines the number and kinds of species in a
community and the niche each occupies.

Competition
Dividing resources - instead of competing for similar resources
species usually divide them up.
• The 3 species of N. American Warblers live in the same tree
and all eat insects, but all feed on different levels.
p. 101
Competition
By feeding at different areas of the tree, the birds avoid
competing directly with one another for food.
• What would happen if two of the warbler species tried to
occupy the same niche in the same tree at the same time?
