Detailed explanation-1: -It shows how energy and nutrients are transferred from plants (producers) to herbivores and carnivores and through to decomposers . All food chains start with a producer. The arrows in the food chain below depict the direction in which energy and nutrients flow, i.e. the arrow always points from the eaten to the eater.
Detailed explanation-2: -To read the food web: The arrows show what each organism eats and the flow of energy. The arrow points to the organism that does the eating and who GETS the energy.
Detailed explanation-3: -Arrows on a food chain, or food web, represent the flow of energy. The placement of the arrows in a food chain or food web is very important. The arrows always show the direction of the energy as it is transferred from one organism to another. The flow of energy can also be represented within an energy pyramid.
Detailed explanation-4: -In a food chain, energy flows from the producers to the consumers and then to the decomposers. Consumers can eat strictly producers or plants or they can eat both other consumers and producers or they can eat strictly other consumers. The decomposers get their energy from dead and decaying consumers.
Detailed explanation-5: -The arrow always points to the higher trophic level, that is from the prey to the predator and this indicates the flow of energy in the form of food. Energy from one trophic level to another is not completely transferred.
