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

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.

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.

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?
