The biosphere is the part of the earth that supports life. Abiotic influences of an ecosystem: (biotic is anything that is alive: trees, animals, bacteria) Two significant abiotic factors that influence the life in a biome are temperature and precipitation. Temp and precipitation dictates the type of biome the place is. As the latitude, the distance away from the equator, increases, average temperature tends to decrease. From equator: tropical rainforest, temperate deciduous forests, taiga, tundra, polar ice. As the altitude, or elevation from sea level increases, average temperatures decrease. Low to high altitude: tropical rainforest, temperature deciduous deforest, taiga (coniferous forests), tundra,
