Document Summary

Oxygen climatic environmental factors: temperature, precipitation, light, wind temperature. Metabolic processes have a certain temperature range. Indirectly influences the availability of/ demand on resources. Influences animal physiology and need for shelter ectotherms. Cold-blooded animals lack the ability to internally control temperature eg. invertebrates, reptiles, amphibians endotherms. Warm-blooded animals create heat by their metabolism eg. mammals, birds precipitation. Indirectly influences the availability of resources eg. soil nutrients. Distribution of organisms affected by precipitation regime: amount. Seasonal changes in life that trigger life processes. Migration, mating period, diurnal activity (day and night activity) wind. Affects vegetation structure in highly exposed areas eg. limits growth of trees , causes excessive drying edaphic environmental factors: soil. Texture, structure, organic matter, organisms, acidity and alkalinity organic matter. Leaf litter, woody materials that fall on the floor. Humus -rich, dark organic material through decomposition, essential to soil"s fertility geomorphic environmental factors: landforms. Slope steepness = angle relative to horizontal.
