1. Tropical Rainforest
* High Temperature: Warm temperatures year-round (average 20-30°C) due to consistent solar radiation.
* High Rainfall: Abundant precipitation (over 200 cm annually) driven by rising warm air and atmospheric circulation.
* High Humidity: Dense vegetation and abundant precipitation create a humid atmosphere.
* Sunlight: Sunlight penetrates the canopy only in patches, creating distinct layers of vegetation.
* Soil: Thin, nutrient-poor soil due to rapid decomposition and nutrient leaching.
2. Savanna
* High Temperature: Warm temperatures year-round with a distinct dry season.
* Seasonal Rainfall: Seasonal rainfall patterns (often less than 150 cm annually) create distinct wet and dry seasons.
* Sunlight: Abundant sunlight exposure due to the open grassland structure.
* Soil: Well-drained, nutrient-rich soils.
3. Temperate Grassland
* Moderate Temperature: Distinct seasons with warm summers and cold winters (average 0-20°C).
* Seasonal Rainfall: Moderate rainfall (50-100 cm annually), often concentrated in spring and summer.
* Sunlight: Abundant sunlight exposure due to the absence of large trees.
* Soil: Deep, fertile soils rich in organic matter.
4. Temperate Deciduous Forest
* Moderate Temperature: Distinct seasons with warm summers and cold winters (average 5-20°C).
* Moderate Rainfall: Consistent rainfall throughout the year (75-150 cm annually).
* Sunlight: Sunlight penetrates the canopy in spring and fall when leaves are absent, but less so during summer.
* Soil: Rich, fertile soils with significant leaf litter decomposition.
5. Temperate Coniferous Forest (Taiga)
* Low Temperature: Cold, long winters and short, cool summers (average -20°C to 20°C).
* Moderate Rainfall: Moderate rainfall (30-100 cm annually), often in the form of snow.
* Sunlight: Sunlight penetrates the canopy in winter, but less so during summer.
* Soil: Thin, acidic soils with slow decomposition rates.
6. Desert
* High Temperature: Extreme temperature fluctuations, with hot days and cool nights.
* Low Rainfall: Very low precipitation (less than 25 cm annually).
* Sunlight: Abundant sunlight exposure due to clear skies.
* Soil: Sandy or rocky, low in organic matter.
7. Tundra
* Low Temperature: Very cold temperatures year-round (average below -10°C) with permafrost.
* Low Rainfall: Limited precipitation (less than 25 cm annually).
* Sunlight: Limited sunlight hours during winter with extended daylight hours in summer.
* Soil: Permafrost, a permanently frozen layer of soil.
8. Freshwater Biomes (Lakes, Rivers, Streams)
* Water Temperature: Varies depending on location and season.
* Water Flow: Currents and flow rates vary depending on the body of water.
* Dissolved Oxygen: Levels can fluctuate depending on temperature, current, and plant life.
* Nutrient Levels: Varies significantly depending on surrounding land use and water sources.
9. Marine Biomes (Oceans)
* Water Temperature: Varies greatly depending on depth, latitude, and currents.
* Salinity: High salt content.
* Sunlight: Sunlight penetrates the ocean surface but rapidly decreases with depth.
* Dissolved Oxygen: Levels vary with depth and current patterns.
Note: Abiotic factors interact and often influence each other. For example, temperature can affect rainfall patterns, and rainfall can influence soil type.
