'sapros' refers to rotten and 'trophic' refers to food. Saprotrophic nutrition is the process by which the organisms feed on dead and decaying matter. The food is digested outside the cells or even outside the body of the organism - extracellular digestion. The organism secretes digestiv..

Carbon Dioxide - Occurrence - Jan Baptista van Helmont discovered the presence of carbon dioxide in the year 1630. Although the percentage of carbon dioxide in air is very small, it plays a vital role in nature. All the food that is produced on the earth is by photosynthesis, which employs carbon d..

Photosynthesis is the only process which produces enormous quantities of organic matter for sustaining the life on this globe. It is the only known method of manufacture of organic food from inorganic raw materials. Animals including man are directly or indirectly dependent on p..

Lymphatic System of a Human The lymphatic system is an accessory circulatory system which transports lymph, a fluid similar to plasma from the intercellular spaces of tissues to the blood. It is a one way route for the movement of interstitial fluid to blood. The lymphatic system can carry prot..

Ammonia is produced by decay of plant and animal tissues. Nitrogenous organic matters like urea in the urine and excreta of animals get acted upon by bacteria releasing ammoni..

Water - In the Earth's biosphere, water is essential to all forms of life. Interestingly, it is also the biospheres most abundant compound and a unique substance from the chemical point of view. About 75% of the Earth's surface consists of water. Water is present as either (a) Solid - ice..

Forests and Wild Life - The biotic component of our environment on land, i.e. plants and animals (leaving aside the oceans and other water bodies) are overwhelmingly found in forests. Forests form a buffer for the earth to protect life forms; in fact that's where all o..

The hypothalamus is a part of the brain, situated at the base of the fore brain. It consists of several masses of the grey matter called hypothalamic nuclei, scattered in the white matter. It is connected to the anterior lobe of the pituitary gland by hypophysal portal blood ves..

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 bioti..

b - particle, and reverts to nitrogen In nature, radiocarbon is formed when high energy atomic particles called cosmic rays break down the atoms in the atmosphere into electrons, protons, neutrons and other particles. Some of the neutrons strike the nuclei of nitrogen atoms in the ..
