Food chain and Food web

Food chain and Food web Food chain } Food chains are unidirectional sequence or order of organisms of an ecosystem that the food is passed from one type of organism to other organisms. } All trophic levels in an ecosystem are connected by transferred of energy. } Trophic level- The trophic level of an organism is the position it occupies in a food chain. Energy flow of a food chain is unidirectional i.e. From producer through herbivores to carnivores. } The amount of energy flow decreases with successive trophic level. A large amount of energy (~90%) is lost each trophic level. } Only about 10% of biomass is transferred from one trophic level to the next one in a food chain. Type of food chain- Grazing food chain } Grazing food chain starts from plants, goes through herbivores and ends in carnivores. example: Grass à Grasshopper à Lizard à Hawk Phytop...
