The Biosphere

The Biosphere
2
Ecology

• study of interactions among and between
  organisms and their environment
• Biosphere
• Includes land, air, water and all life
• Extends 8 km above Earth and 11 km below ocean
  surface

3
Levels of Organization

• Biosphere
• Biome group of ecosystems with same climate and
  communities
• Ecosystem
• Community
• Population
• Individual

What is Climate?

• average, year-after-year conditions of
  temperature and precipitation (rain, snow, fog,
  etc) in a particular region
• Affected by
• Latitude (equator vs. poles)
• Transport of heat by winds and ocean currents
• Shape and elevation of land masses (mountains,
  valleys, etc)

Latitude
Indirect sunlight

• Most direct sunlight

7
Ocean and Air Currents

• As air and water are heated they.

Rise!
So, water and air at the equator rise when heated
and fall as they coolcreates currents

Shape and Elevation of Land Masses

• Same thing happens over mountains

and over rainforests near the equator
