Why is it necessary for energy to move the way it does up the food pyramid. this is a science question by the way.

The number of times that a species at a higher trophic level consumes food rises when you travel up the food pyramid, so more food should be accessible from the lower levels in order to provide the necessary energy.

Step-by-step explanation:

The use of an energy pyramid n the food chain explains the transition of energy from one species to another. The energy reduces when as looks from the base to the top of a pyramid. The pyramid base is higher, and the species at the pyramid base are more common. When you go up the ladder of energy, energy is reducing, and so is the number of species. Plenty of energy losses during the transition of energy to heat. Nevertheless, the energy obtained from food is used to power the metabolic process of organs and tissues, respiration, digestion, and brain functions.

the answer to question 1 is -8, 28.
