Food Web - In nature, food chain relationships are not isolated. They are very complex, as one organism may form the food source of many organisms. Thus, instead of a simple linear food chain, there is a web like structure formed by these interlinked food chains. Such interconne..

Food Webs - In nature, the food and feeding relationships of plants and animals are rarely as simple as the examples of food chains described above, because many animals eat more than one kind of food. On this account, different kinds of food chains overlap each other or intercross each o..

All radioactive decays follow first order kinetics. Therefore, the half-life of a radioactive element is independent of the amount of sample. With the help of half-life values of a suitable radioisotope of an element, which is present in a rock, or in an artefact, the age of the rock and the ..

While studying the biotic components in an ecosystem we have realised that food prepared by green plants is consumed by a series of consumers, both herbivores and carnivores, and finally broken down into their elements and released back into nature by decomposers in natur..

Radiocarbon dating of historical wooden - derived objects is based on the knowledge that the cosmic ray intensity (responsible for 1 4 C production) has been practically constant for thousands of years. 1 4 C is formed in the upper atmosphere by the action of cosmic radiation ..

Radiocarbon The 1 4 C so produced is eventually converted into CO 2 , which in turn is incorporated into plants and trees by the process of photosynthesis and then finds way into animals, which eat plants. As there is a natural plant-animal cycle, an equilibrium is set up and all living matter cont..
