1

Distribution of major ecological communities is determined by _____ + _____

Temperature and Precipitation

2

1) Differences in the amount of solar radiation falling on earth's surface
2) The earth's daily rotation on its axis and yearly revolution around the sun
3) The distribution of the earth's continents and oceans
4) The elevation of land mass
