Detailed explanation-1: -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: -The level of the food web that has the most energy is the producers, according to the 10% rule. Producers are organisms that make their own food, such as photosynthetic plants, algae and bacteria, or chemosynthetic bacteria. Thus, since producers make their own food, they can get 100% of the available energy.

Detailed explanation-4: -Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
