Early morning, sometime in the future. A team of surgeons removes the heart, lungs, liver, kidneys and pancreas from a donor, whereupon a medical technician packs these organs in ice and rushes them to a nearby airport. A few hours later the heart and liver land in one city, the two kidneys in another, and the lungs and pancreas arrive in a third. Speedily conveyed to hospitals in each city, these organs are transplanted into patients who are desperately ill. Back at the donor center, surgeons repeat the procedure several times. In all, surgical teams scattered throughout the U. S. conduct more than 100 transplant operations on this day alone. How could so many organ donors have possibly been found? Easily, by obtaining organs not from human cadavers but from pigs!

Ecology

The Biosphere Chapter 34

What is Ecology? • Study of the interactions of organisms with each other and their surrounding environment • Can be studied at many levels • • Global Within a biome Within a local environment Even within a large animal

Levels of Organization

Climate Influences Biological Distribution • • • Biomes are determined by climate Climate is affected by amount of sunlight per day/season Amount and type of precipitation Temperature Geological formations (terrestrial biomes) Gulf streams (aquatic biomes)

Uneven Distribution of Sunlight

Seasons are Caused by the Earth’s Tilt

Tropics Receive More Rainfall

Prevailing Winds
