A good example could be a food chain. If plants couldn’t make their own food using photosyenthessi. There wouldn’t be any producers left in the ecosystem. Once there’s no producers, the rest of the food chain gets affected. There wouldn’t be any food for the primary consumers (herbivores). Gradually the primary consumers would die down. One by one. Eventually there wouldn’t be any food for the secondary consumers (Carnivores) because there aren’t any primary consumers. The same situation relates to the a food web.
The energy pyramid shows many trees and shrubs providing food and energy to giraffes. Note that ass we go up, there are fewer giraffes than trees & shrubs and even fewer lions than giraffes … as we go further along the food chain, there are fewer and fewer consumers. In other words, a larger mass of living things at the base is required to support a few at the top … many herbivores are needed to support a few carnivores.
