Solution:

Temperature is the most ecologically relevant environmental factors. Average temperature on land varies seasonally, and progressively decreases from the equator to poles. Organism which can survive in wide range of temperature are called as eurythermals. The productivity and distribution of plants is also heavily dependent on water.
