why do bodies decompose

They are the saprophytic and saprozoic organisms that decompose the dead plant and animals before feeding on the..

There are saprophytic organisms (mainly bacteria and fungi) that live on dead animals and plants. In terrestrial ecosystem, bacteria act on animal tissue and fungi on plants but there may be exceptions also. This group of organisms plays a vital role in releasing back the biotic components into th..

The general body cavity which is called coelom gets partitioned into numerous cavities. Following cavities (not necessary coelomic) can be recognised in the body..

Floating Bodies - Usually, all bodies less than that of water float, bodies which are denser than water sink. You might have noticed that a piece of steel sinks, but a ship made of steel floats. This is because of the design of the ship. The steel body of the..

is defined as the amount of matter contained in it. The SI unit of mass is kilogram (kg). Mass is a scalar quantity. The amount of matter contained in a body does not change with time or from place to place i.e., mass of a body remains the same throughout the universe. Howe..

The shape of many objects moving through air or water is designed in such a way that friction between the objects and the medium through which they move is minimised. Aeroplanes, boats and paper rockets are examples of streamlined objects. Aeroplane B..

The body cavity is a true coelom since it is lined by a layer of coelomic epithelium of mesodermal origin. The coelom is filled with a watery fluid called coelomic fluid which encloses atleast 4 different types of cells (=corpuscles) Phagocytes which can ingest disease producing pathogens..

The sound of a tuning fork or a vibrating string in air is more intense when placed on a sound box which undergoes forced vibratio..

If you have ever mowed the lawn using a mower, you would have noticed that pushing the mower is more difficult than pulling it. Have you ever wondered why? Let us try to understand this by a simple block and plane example. When the block is pushed, the vertical component of the push incr..
