Ultimately - the Sun... The heat from the sun causes water to evaporate. This forms clouds - which create rain. The rain falls to earth and is eventually evaporated by the Sun... The cycle continues !

Branches of ecology include population ecology (study of how populations of organisms interact with their environment), community ecology (study of interactions between species in a given area), ecosystem ecology (study of the flow of energy and matter through ecosystems), and conservation ecology (study of how to protect and preserve biodiversity).
Related disciplines and approaches under ecology include environmental science, conservation biology, population ecology, community ecology, landscape ecology, and ecosystem ecology. These disciplines study interactions between organisms and their environment at different levels of organization, from individuals to ecosystems, to understand how ecosystems function and how they can be managed and conserved.

because if theres no river no rain

The sun is outside of the Earth but the rain happens on the Earth.
Rain from the Sun was created on 2006-06-01.
because in rain there is cold so we got sunshine from sun

Because when the observer is between the sun and the rain droplets the sun hits the rain droplets and then the rain droplets bend and form the colours.
