Unit 2 Lesson 5- Energy Flow in Ecosystem-Trophic Levels, Food Chain & Food Web

By Sadiq'sir

Sun is the primary source of energy for all ecosystems on Earth. Of the incident solar radiation less than 50 per cent of it is photosynthetically active radiation (PAR) .  Photosynthetically active radiation , often abbreviated PAR , designates the spectral range (wave band) of solar radiation from 400 to 700 nanometers that photosynthetic organisms are able to use in the process of  photosynthesis.   Plants capture only 2-10 per cent of the PAR and this small amount of energy sustains the entire living world. The energy of sunlight fixed in food production by green plants is passed through the ecosystem by food chains and webs from one trophic level to the next. In this way, energy flows through the ecosystem. The Trophic Structure of Ecosystems The organisation and pattern of feeding in an ecosystem is known as the trophic structure. =>   The levels through which food energy passes from one group of organism to the other...
