Why are there fewer organisms in each level as you go up the energy pyramid ​
SVETLANKA909090 [29]

Explanation: The energy pyramid describes how energy gets distributed through an ecosystem. The more there is of an organism on the energy pyramid, the more it gives overall to the ecosystem. The less there is of an organism, the less it gives to the ecosystem. Take the Floridian Everglades as an example. There is an abundance of sawgrass, and that makes up the foundation of the system, along with mangroves and such. But there are less of predators in the ecosystem because they only feed of of their prey like small mammals or fish. They never start the food chain, they end it.
