Astudent drew this model of the trophic levels of an ecosystem. how can you improve this model’s accuracy?

the sun should be added at the bottom, with 100 percent of the energy.
the energy retained should decrease from the bottom of the pyramid to the top.
the energy retained should be equal from the bottom of the pyramid to the top.
the sun should be added at the top, with 100 percent of the energy.

can be multiple answers

the energy retained should decrease from the bottom of the pyramid to the top.

A food chain is a linear series of events in an ecosystem in which one organism is fed by another organism in order to make by their nutritional and energy requirements. A food chain includes trophic levels according to different types of feeding organisms. The energy distribution among these trophic levels takes place according to the 10% law. The law suggests that energy from lower trophic level in the food chain decreases in subsequent higher trophic levels.

it is called the mitotic spindle
