energy through ecosystems

An ecosystem is a self sustaining structural and functional unit of the biosphere. The ecosystem may be large or small. In the biosphere several ecosystems exist. Usually there is exchange of material and energy between adjoining ecosystems. Ec..

In an ecosystem there are two processes proceeding simultaneously: 1 ) Energy flow and 2 ) Biogeochemical cycle The energy flow is in a single direction and is non-cyclic where as Biogeochemical flow is cyclic (Any mineral cycl..

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..

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 fo..

Energy is the capacity to do work. Solar energy is transformed into chemical energy by the process of photosynthesis, and is stored in plant tissue and then transformed into mechanical and heat forms during metabolic activities. The energy, in the biological ..

Generating energy to meet the demands of human being is one of the greatest interferences of human beings on the nature. Any form of generating energy leads to imbalance in natural eco-systems. Some of such imbalances will cause pollution. Out of important methods of h..

Pyramid of Energy - "Pyramid of energy is a graphic representation of the amount of energy trapped per unit time and area in different trophic level of a food chain with producers forming the base and the top carnivores at the tip". Pyramid of Energy in a Foo..

Energy Flow - All living beings require a constant supply of energy for the various functions they perform. The energy is obtained from the sun. This energy is introduced into the biosphere by green plants by a process known as photosynthesis. Plants are able..

. Hence, energy flows from sun through producers to consumers in a single direction only. The decreasing energy level at each step sets the limit of trophic levels to a maximum of 4 or 5. It is the continual trapping of light energy by green plants that makes good this..

Laws Governing Energy Transformations - The storage and expenditure of energy in an ecosystem is in accordance with the laws of thermodynamics (basic laws of thermodynamics). The first law of thermodynamics is the law of conservation of energy, which says tha..
