Answer:
Oceanic crust is younger crust . Well, It is because, an oceanic crust is formed when a continental crust undergoes a big tension crack due to the forces generated inside the earth, which may be because of the magma dwelling inside. As the crack becomes prominent, the continent is broken into the segments with a big oceanic basin kind of structure between them (This takes millions and millions of years). Sediments deposit in the basin and get stratified to form the oceanic crust. This is the reason that oceanic crust is younger than the continental crust.
Fungi join bacteria as the primary decomposers in different ecosystems. They feed on the organic remains of dead plants. They release special enzymes that break down lignin, a structurally complex substance in wood. Decomposing organic matter is considered by ecologists as the major ecological role of fungi.
