Ecology Flashcards
Chapter 6
What is Ecology
The study of the reationship between living organisms with each other and their non-living environment
Biosphere (Ecosphere)
The part of the earh and it atmosphere inhabited by living organism
Terrestrial Biomes
Naturally occurring communities occupying distinct regions of the Earth’s land
How are Terrestrial Biomes Classified?
Climate,
Vegetation
Animal life
influenced by factors such as temperature, precipitation, and latitude.
Characteristics of Tropical Rain Forest
-Formed in hot regions (24 - 28°C)
-Layers of trees
-The ground floor is dark with sparse vegetation
-Many organisms live in the canopy
-Soil quality is poor because decomposition occurs quickly, and nutrients are either taken up by trees or washed away
Characteristics of Temperate Deciduous Forest
-Hald the year has a winter so cold that no life can survive
-Organisms that live here have developed methods of surviving the winter
-Ex: Migration, dormant stage. hibernation
Characteristics of Desert
-Characterized by sparse irregular rainfall and sandy soil
-Organisms that live here have developed ways to survive during harsh conditions
Ex: Short life cycle, resistance to dehydration, ways to store water, broad feet to walk on sand(camel)
Charteristics of Tundra
Aquatic Biome
Which Characteristics effect aquatic biomes
-Salinity
-Nutrient Availability
-Depth of water
-Permanency of water body
-Tide Strength
