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 ..

Food Chains and Food Webs - 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 an..

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 nature. The ..

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 o..

2 per litre of water. A weak organic waste has a BOD less then 1500 mg/ litre, a strong one has higher than this. A survey of the river Yamuna recorded BOD of 2000 at Delhi, 9000 at Mathura and 12,000 at Agra. Shifts in biodiversity of animals and plants in polluted ecosystem. Imbalance ..

The organisms, in addition to being dependent on the environment for their needs, are also dependent on each other. This dependency is especially for food. This results in the presence of food chains and food webs..

The study of food chains helps in understanding some of the important aspects of the ecosystem in particular and environment in genera..

Biomass is the living matter in any organism. It is the amount of living time or energy available as food for the organisms of the next trophic level. The mass of organisms in each trophic level is called the standing cro..
