Decomposers break down the remains of dead plants and animals and take the nutrients and energy and give it back to the earth when they die.
Plants converts solar energy into chemical energy through the process of photosynthesis . The electron and proton from the water molecules are used to produce energy transport molecules i.e ATP and NADPH, in the light reaction phase of photosynthesis. The energy of the sun excites the chlorophyll molecule which in turn release high energy electron. The energy of ATP and NADPH is further used to fix the carbon in the Kelvin cycle.
It is called ecological succession, which can take up to a decade. It is a process of change in the species structure that occurs after a vast loss or extinction. Ecologists study how complexity is evident when a community is formed or occurrence takes place from an empty land or bare soil.
