it would be 20 calories = 10%

In a food chain, energy transfer between trophic levels typically follows the 10% rule, meaning only about 10% of the energy from one level is passed on to the next. If a snake receives 200 calories from eating a rabbit, it would likely utilize some of that energy for its own metabolic processes, leaving around 20 calories available. Therefore, if a hawk then eats the snake, it would receive approximately 20 calories of energy.
5 would be passed on to the hawk.

The hawk would receive about 5 of the plant based calories.
Every step of energy transformation have loss. Progress through the energy chain, the amount of energy transferred would unavoidably degraded. So as the chain progress it get narrower to a pyramid shape.
In an ecosystem energy passes from one feeding level to another. Producers are plants that occupy the first level in the ecosystem. They are the only organisms that can convert the sun's energy into chemical energy through photosynthesis. When plants are consumed, energy is passed on the herbivores and then carnivores. Without producers in the food chain there would be no energy produced for other consumers of the food chain, which is vital to daily life.

Producers are important for the transfer of energy within an ecosystem because they are capable of converting sunlight into chemical energy through photosynthesis. This energy is then passed on to consumers within the ecosystem through the consumption of the producers. Without producers, there would be no initial energy source for the rest of the ecosystem.
