Describe how energy flows through each levels in the energy primed is all the matter and energy from one level transferred to the next level

The energy flows from one level to the another level in energy pyramid in the following form.

The first trophic level organisms are the plants. They are called producer because they produce food for themselves and for others from the process of photosynthesis. These plants are eaten by primary consumers i.e. herbivores and the energy which is present inside the plant is transfer to animals. Herbivores are eaten by secondary consumers i. e. carnivores. After that secondary consumers are the food of tertiary consumers.

No, all the matter and energy from one level doesn't transferred to the next level. 90 % of energy is lost as a heat energy and 10 % is transfered to next level.
