abiotic factors in the savannah biome
Best Results From Wikipedia Yahoo Answers Youtube
In biology, abiotic components are non-living chemical and physical factors in the environment. Abiotic phenomena underlie all of biology. Abiotic factors, while generally downplayed, can have enormous impact on evolution. Abiotic components are aspects of geodiversity.They can also be recognised as "abiotic pathogens"
From the viewpoint of biology, abiotic influences may be classified as light or more generally radiation, temperature, water, the chemical surrounding composed of the terrestrial atmospheric gases, as well as soil. The macroscopic climate often influences each of the above. Not to mention pressure and even sound waves if working with marine, or deep underground, biome.
Those underlying factors affect different plants, animals and fungi to different extents. Some plants are mostly water starved, so humidity plays a larger role in their biology. Many archaebacteria require very high temperatures, or pressures, or unusual concentrations of chemical substances such as sulfur, because of their specialization into extreme conditions. Certain fungi have evolved to survive mostly at the temperature, the humidity, and stability.
For example, there is a significant difference in access to water as well as humidity between temperate rainforests and deserts. This difference in water access causes a diversity in the types of plans and animals that grow in these areas.

Answers:Fire, ground water, water table, soil's moisture retention, landforms (plateau, mountain, valley) and their slope ( < 3% to > 10%), soil temperature, days of cloud cover versus days of sun for amount of sunlight and it influence, first & last frost dates for growing season. Focus on the limiting factors of the air supply, precipitation, soil types, & light. Savanna grasslands tend to have porous soil with good drainage. However the top soil layer is very thin. The exact texture of the soil minerals depends on the bedrock. Savannas usually form soil by laterization. http://www.uwsp.edu/geo/faculty/ritter/geog101/textbook/soil_systems/soil_development_processes.html http://www.physicalgeography.net/fundamentals/10u.html This creates edaphic conditions or soil influenced by physical, chemical or biological factors that influence the final composition of the community. The soil structure depends on the soil fauna community or the edaphon. If the soil is very oxidized and acidic it will support a strongly fungal community compared to a neutral pH in a soil that supports more bacteria. The plant community will rely on their mycorrhizal (a beneficial soil fungus) symbionts to extract nutrients. http://www.blackwell-synergy.com/doi/abs/10.1111/j.1469-8137.1992.tb02948.x http://www.springerlink.com/content/r60gtl28h5q77g0r/

Answers:1. Available energy, i.e., sunshine 2. Available water 3. Available inorganic nutrients, e.g, iron, phosphorus, fixed nitrogen. 4. Temperature The availability of these is somewhat different depending on which biome you choose.
