What is the process of matter changing from a solid to a liquid state

Melting, the solid reaches it's melting point and thermal energy is used to break bonds and overcome the strong forces of attraction to become liquid.

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
