![“When a caterpillar eats a leaf, then a thrush eats the caterpillar, or when a hawk eats the thrush only 5 to 20% of usable energy is transferred from one level to the next. ... Thus herbivores will account for a much smaller fraction of the biomass [than plants] and the carnivores for a still…” quote by Richard Heinberg](https://sms4smile.com/quotes/img-quotes/5a7/richard-heinberg-28724_accounts_when-a-caterpillar-eats-a-leaf-then-a-th_1543538.jpg)
