Which of the following statements about flows is true? they include herbivory and decomposition, and energy is lost at each flow they include the water and nitrogen cycles, and matter is lost at every flow they include carnivores and plants, and energy cycles continuously through each flow they include phosphorus and carbon dioxide, and can cause eutrophication

Solution

The first statement i.e. They include herbivory and decomposition, and energy is lost at each flow is true. The energy flows in a unidirection from sun to plants to herbivores to carnivores and to decomposers. But in this flow of use of energy, most of the energy is used up by the organism for different biological purposes and some of the energy is lost as heat. About 10% energy is transferred from one trophic level to another and thus energy is lost at each flow.
