trophic levels in a savannah

Trophic Levels - Each link in a food chain is known as a trophic level. For example, in each food chain, plants always form the first trophic level. The plant eating animals called herbivores like insects, rodents, rabbits, deer, cattle, e..

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 fo..

"Food chain is a series of groups of organisms called trophic levels, in which, there is repeated eating and eaten by so as to transfer food energ..

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..

Although matter circulates, energy cannot be reused indefinitely. Solar energy is converted by the photosynthetic producers (plants) into chemical energy in the form of plant carbohydrates. Herbivores consume the plant carbohydrates and so this chemical energy is transferred to them. Carnivores con..

The characteristic structure of an ecosystem is obtained by the systematic physical organisation of the abiotic and biotic components of that particular ecosystem. The two main structural features of any ecosystem are its 'species composition' and 'stratification'. An ecosystem can be represented b..

Energy conserving efficiency is 1.5% for grassland, 0.9% for savannah, 0.81% for mixed forest, 5% for modern crops and 10 - 12% for sugarcane field. Thus in an ecosystem there is, a) constant flow or transfer of energy from sunlight through plants (producers) to animals (consumers) in the..
