EVERYDAY SCIENCE

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. Ex: the snowy owl eats the artic hare and the lemming. The owl gets its energy from the hare and the lemming.

Detailed explanation-3: -The energy stored in the plants through photosynthesis is transferred to herbivores that feed on the plants. From herbivores, energy is transferred to carnivores that feed on them. So the direction of the flow of energy is from the sun to the carnivores.

Detailed explanation-4: -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-5: -The arrows on a food chain indicate where energy is being passed. For example, an arrow pointing from some grass to a zebra means the grass gives energy to the zebra (when the zebra eats the grass). The arrows on a food chain indicate where energy is being passed.It also specifies the direction of the flow of energy.
