Answer:
Each trophic level represents the beings of an ecosystem and their amount of energy.
Explanation:
In a food chain, the highest energy level is made up of producers (e.g. chlorophyll plants), with the rest of the ecosystem dependent on their energy, captured from sunlight and stored in organic compounds.
The next trophic level belongs to primary consumers (herbivores) and then secondary consumers (carnivores).
From the producers, only part of the amount of energy is passed from one trophic level to the other, In other words, the higher the trophic level, the less energy is absorbed.
In an energy pyramid, each area is represented by a trophic level (from a food chain) of size proportional to its amount of energy.
The elements of the food chain are represented with the producers at the base (higher energy) and the consumers of each trophic level above.
As explained earlier, the amount of energy absorbed at the highest levels is low and therefore insufficient to support another trophic level.
A heart attack happens when a coronary artery becomes out of no where in a instant blocked and it stops the flow of blood to the heart muscle and starts to damage it.
