INTRODUCTION TO ECOLOGY BIOLOGY CHAPTER 3-1 UNIT CH 3 THROUGH CH 6
ECOLOGY The scientific study of interactions among organisms and their environment.
ORGANISM A living creature (Bufo americanus)
POPULATION A group of organisms that live together same species: geese (Branta canadensis)
COMMUNITY Groups of Populations Different species living together Zebra, lions, elephants
ECOSYSTEM Self sustaining collection of organisms Biotic factors: Living components Abiotic factors: Nonliving components
HEALTHY ECOSYSTEMS Diversity More diverse = More Stable the environment Every animal has a specific role (Niche)
UNHEALTHY ECOSYSTEMS Little or no diversity Ecosystem is more susceptible to diseases No organisms left to use or appreciate
HOW DO WE GET DIFFERENT ECOSYSTEMS? Sun provides energy to Earth Equator: direct sunlight Poles: low angle of sunlight
HOW DO WE GET DIFFERENT ECOSYSTEMS? Tilt of the Earth creates seasons
BIOMES Broad geographic regions Characterized by climate & major vegetation Aquatic Biomes: 75% of Earth Terrestrial Biomes: 25% of Earth
TROPICAL RAINFOREST Equatorial regions 200-400 cm rain/year 25-29 ° C Species diversity extremely high
DESERT Near 30 ° N and S latitude Less than 30 ° cm rain/year Wide fluctuations in temperature Many species nocturnal
SAVANNA Equatorial regions Rainfall is seasonal 24-29 ° C Primarily grassland
CHAPPARAL Mid-latitude coasts Rainfall is seasonal Moderate year round weather High diversity of amphibians
TEMPERATE GRASSLAND Central North America 30-70cm rain/year (droughts common) Cold winters, Hot summers Historical IL Biome
CONIFEROUS FOREST Taiga Northern hemisphere 30-70cm rain/year Cold long winters Short warm summers Cone-bearing trees
TEMPERATE BROADLEAF FOREST Deciduous Forest Mid-latitudes of Northern Hemisphere 70-200cm rain/year Average winters, hot humid summers
TUNDRA Northern hemisphere 60cm precipitation/year Winters are long cold, summers short cool 20% of terrestrial surface
