Nutrients - Just as the human body needs nutrients for its healthy growth, plants also need certain nutrients for their growth. The nutrients required by plants for their healthy growth are 16 in number. They are carbon, hydrogen, oxygen, nitrogen, phosphorus..

Just as the human body needs nutrients for its healthy growth, plants also need certain nutrients for their growth. The nutrients required by plants for their healthy growth are 16 in number. They are carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, ..

The nutrient movement goes on side by side along with unidirectional flow of energy. The nutrient movement is a cyclic movement where the nutrients revolve round with an ecosystem, hence cyclic. This cyclic movement of nutrients is also called as biogeochemi..

Phosphorus is an essential nutrient to biological systems. Its requirement is mainly seen in nucleic acids, cell membrane, bones and tee..

' (bio - living organisms; geo - soil, rock, etc, chemicos - elements and their compounds). These materials have been used again and again in the formation of new generations of the organism. In other words, the matter is continuously recycled. By definition, "The movement or circulation of biogene..

Organic materials synthesised by the producers are eaten and assimilated by the consumers. With the help of decomposers, all the organic materials in the bodies of the consumers are eventually broken down into inorganic materials. These are then rebuilt into organic compounds by the synthetic activ..

Summary - The biotic and abiotic components form an interacting system called 'ecosystem'. Producers, consumers and decomposers are the various trophic levels, which are linked by their food relationship forming a 'food chain'. Several food chains are interrelated and interconnected to form a netwo..

. Thus a single cell can develop into a whole organism or in other words, the cell is totipotent. This is because it contains the full set of genetic information needed to make the organism. This is called cellular totipotency. Thus, a tissue can be taken from any part of the plant and put in a sui..

Summary - According to the modified cell principle, new cells arise only from pre-existing cells. Cells transfer their genetic information only by way of cell division. The mode of cell division is largely the same in all living organisms indicating the unity of life. Cell division becomes necessar..

Summary - The circulatory systems circulate nutrients, wastes and metabolic intermediates and heat uniformly through out the body. Advanced animals carry blood as the circulating fluid and a circulatory system with the heart and blood vessels to conduct the blood. In invertebratessuch as ..
