Food chains are sometimes short because most of the energy in a trophic level is lost as it passes to the next higher level
Because just one type of herbivore consumes each kind of plant, food chains can occasionally be short.
The process of energy transferring between species within an ecosystem is known as energy flow. Producers—vegetation having the capacity to harness solar energy—are where the process begins. Following herbivore consumption of this plant, omnivores and predators devour it as well.
A short food chain is caused by a limited supply of food energy, which is substantially reduced at each trophic level. There may not be enough species in a low biodiversity habitat for a complex food chain.
