Study Notes
Desert Ecosystems
- Characterized by low rainfall (<25 cm/year) and high temperatures
- Limited vegetation, dominated by cacti and succulents
- Adaptations:
- Deep roots to access water
- Waxy stems to reduce water loss
- CAM photosynthesis (open stomata at night)
- Fauna:
- Reptiles, insects, and small mammals
- Adaptations:
- Camouflage and burrowing to escape heat
- Specialized physical features (e.g., camel's hump)
Tropical Rainforests
- Characterized by high temperatures and high rainfall (>200 cm/year)
- High biodiversity and dense vegetation
- Stratification:
- Emergent layer: tallest trees
- Canopy layer: dense foliage
- Understory layer: shade-tolerant plants
- Forest floor: limited vegetation
- Fauna:
- Monkeys, birds, and insects
- Adaptations:
- Bright colors and mimicry for camouflage
- Specialized diets (e.g., fruit-eating birds)
Tundra Ecosystems
- Characterized by cold temperatures, short growing seasons, and low rainfall
- Low vegetation, dominated by grasses, mosses, and lichens
- Permafrost: frozen soil that limits root growth
- Fauna:
- Herbivores (e.g., caribou, reindeer) and carnivores (e.g., arctic fox)
- Adaptations:
- Thick fur and blubber for insulation
- Migration patterns to find food and shelter
Savanna
- Characterized by grasslands with scattered trees
- Tropical and subtropical regions
- Seasonal rainfall and drought
- Fauna:
- Grazing animals (e.g., zebras, antelopes) and predators (e.g., lions, cheetahs)
- Adaptations:
- Migration patterns to find food and water
- Specialized physical features (e.g., giraffe's long neck)
Taiga (Boreal Forest)
- Characterized by coniferous forests (e.g., spruce, fir) and cold temperatures
- Subarctic regions
- Short growing seasons and limited vegetation
- Fauna:
- Herbivores (e.g., moose, deer) and carnivores (e.g., wolves, bears)
- Adaptations:
- Thick fur and fat reserves for winter
- Specialized diets (e.g., berries, nuts)
Boreal Forest (Taiga)
- Same characteristics as Taiga
- Note: Taiga and Boreal Forest are often used interchangeably, but some sources distinguish between them as separate biomes.
Ecosystem Characteristics
- There are five types of ecosystem characteristics: dominant vegetation, climate, geographic location, and soil characteristics.
- Each ecosystem can be matched with one of these characteristics.
Types of Ecosystems
- Multiple ecosystems can be identified, including but not limited to:
- One with a distinct dominant vegetation
- One with a unique climate characteristic
- One with a specific geographic location
- One with distinct soil characteristics
