At the Earth's surface, rocks usually break quite quickly, but deeper in the crust, where temperatures and pressures are higher, rocks are more likely to deform plastically.

Fungi lacks the ability to produce their own food because they do not have chloroplast which is needed to obtain energy from the sun and convert it into food.

Because of these they have to depend on dead organic matters for food.
