The biosphere: studying the biosphere contributes to the study of ecology. Forrest: abiotic factors (for uneven distribution) to consider, the distribution of dry land is not uniform. There is more land in northern: seasons are caused by uneven solar radiation, which is caused by the tilt of. Hemisphere vs southern hemisphere, so we can assume there are more organisms in the northern hemisphere. Earth"s axis as it rotates around the sun. This means that the intensity of sunlight gases, which lowers the amount of radiation that reaches earth"s surface. is lower at higher latitudes. This accounts for temperature differences between the equatorial habitats and your more northern or more southern areas. Radiation from the sun is spread over more surface area at higher latitudes, so its intensity is lower. The light rays also have to pass through more atmospheric prevailing winds. There are areas where air rises as it warms up, then sinks as it cools.
